Topic for feature requests

This software has been fantastic, and you have single-handedly helped me enjoy my photography experience again. The slow process of culling photos has been such an energetic drain on my enthusiasm, and I felt trapped under a growing mountain of photographic backlog.
After using the software for while,  I have a few thoughts on possible future feature requests:

• On the filmstrip view, when selecting multiple photographs and using a keyboard shortcut, it applies only to the active enlarged photo, not all selected (I.e move to rejected). It would be nice to have the keystroke apply to all selected photos in filmstrip mode. 
• Echoing the request from others in this thread, additional filtering options would be excellent; I.e: filter by lens type, camera body, keywords, and logic (filename/keywords do/NOT contain)
• File Renaming / Metadata modification. I current mass-select and send to external program MetaImage to modify exif externally. I need this for several reasons: sometimes multiple cameras from a shoot have a consistent offset of internal time (I.e one camera is 1 hour ahead). I also shoot film, so I update the scanned file's exif with info like film emulsion (as a keyword), date shot, camera body, etc. 
• Keywords beyond color labels and star ratings. 
   

This software is brilliant and these are things I can work around. However, with the changes above, I would be less reliant on external applications. Thank you!!

Hi Xasan,
I have the "Single File Keys Work for Multiple Files too" option enabled. The key actions (such as move files) will work on all selected files in grid view, but it will only affect the displayed image in single image mode while the filmstrip is in view. I am a new user, and I'm using the v1.70 beta. Perhaps the behavior is different in this version?

Instance Number to differentiate between two (or more) open instances of FRV.
Opening up a second instance of FRV in order to compare two photos "side-by-side" is very handy. I don't actually compare them side-by-side, instead I put both instances full-screen and then Alt-Tab quickly between the two instances to compare two similar images. For example, assume I have two similar images and I want to pick the "better" of the two (better focus, composition, etc.). I find it easier to "swap back and forth" between the two using Alt-Tab to swap between two open instances of FRV, one instance has image A open and the other instance has image B open.
It would be very helpful if you could display an "instance number" in the FRV title bar (like a big 1 and a big 2) so I can remember which is which. 
Hope that request makes sense.

Update image XMP Metadata whenever the XMP sidecar file size/date changes.
Refering to process in the request above, where I have multiple instances of FRV open in order to quickly Alt-Tab between them as a way of quickly comparing a set of similar images...
Once I find the image I want I will mark it with a star rating and a colored label. Obviously, this makes it easy to see the "picked" images in the filmstrip bar at the bottom of the screen. Unfortunately, the filmstrip is only updated in the instance of FRV in which you made the start and label selections. In other words, if I mark an image with a star rating and colored label in instance A of FRV, when I Alt-Tab to instance B of FRV I do not see those updates on the filmstrip. If I select an image in the FRV B instance I will see in the XMP Metadata panel the selections for that image that I made in the FRV A instance, but those changes to the XMP are not updated in the filmstrip. 
I guess you could call this a bug, but it's probably something that was not thought about in the context of multiple instances of FRV being used like this. I'm simply asking that if an instance of FRV sees that a sidecar file has been updated (new date/size) it would be great if FRV would reread and update the display elements in the FRV UI that are impacted by the updated XMP data.
p.s. Thanks for a terrific product!!

Favorite Folders don't work with network drive
I have setup a Linux Samba file server on which I organize my photos for editing, storage, backup, etc. My network connection between the Windows machine on which I run the FRV software and other photo editing software is fast enough that I don't need to have all the image files stored locally on my Windows editing machine, I just edit directly on the Linux Samba server. This means that I reference the folders using Windows UNC notation, for example: \\samba\Pictures\...
I can save a Windows UNC name in the "Favorite Folders" panel, but it only opens the top-most "root" folder of the Samba server. In other words, it opens the Samba server's files but always at the very top-level (e.g., \\samba) not at the level in the file hierarchy that I have saved in the favorite (e.g., \\samba\Pictures or \\samba\Pictures\2020\folder-name).
Is there a way to fix this? It would be very handy if you could save a complete external file reference as a "Favorite Folder."

Infrequently, I might find an image sequence that would make a good animated GIF, and so I combine several shots into an animated sequence using an external editor.
 
I noticed that displaying the resulting GIF is not supported by FastRawViewer. It would be nice to see this image format supported in the grid view, rather than seeing the "decoding error" thumbnail. I know this is possibly outside of the scope of this application, but this file format is natively viewable on both Windows and Mac OS. Supporting GIF files would add to the completeness of displaying images found within a folder.

Happy New Year!

Great Software
I first will say that the software is exceptional. A few comments, very minor ones, it would be nice if the bottom bar contrast setting used the +/- icons like the EV selection instead of the Up/down arrows. It makes it totally consistant then. And if the contrast control worked the same as the EV where you can toggle contrast change on or off by selecting the center number as it does in the EV.
 

Default-Crop (Aspect Ratio)
It would be nice if the Default-Crop for a RAW-Image could be applied. For example if I take a Photo in RAW and set the Ratio from i.e. 3:2 (native sensor ratio) to 16:9 (Default-Crop) the RAW and also the embedded JPG has still the native sensor ratio of 3:2. This behaviour is as far as I know identical for all Camera-Manufactors.
If I open the RAW in Adob Bridge or Lightroom the Default-Crop will be aplied by default.
I already invested some time how it could work and I found die apropriate EXIF-Data for Olympus und Canon via EXIF-Tool (https://exiftool.org/).
I am also able to give support for this feature, or if it would be possible write a PlugIn for it.

Great program, so please take these suggestions as ways to extend beyond the features it already does well:
 
Depending on the ultimate goals of the developer(s), I'd love to see more digital asset management within this application so that I have to rely on less programs. Some ideas that come to mind:

1. Introduce "Collections" to allow a collection of photos to be collected without changing their storage location. On occasion, I may search through multiple folders to collect a group of photos that will need to be exported for a project. It would be nice to drag and drop the found photos into a collection so that I can see the related photos from different folders.
2. Recreate "Selected" and "Rejected" as an array, with the ability to create additional catagories with the ability for each to create a subfolder or go to a global folder. Use Case: I use "Rejected" as a global 'erase this photo' folder. I use "Selected" as a subfolder reject. It would be nice to be able to create another folder, called "Originals" as the remaining photos may be standing by for edits, and when those edits are done, I'd like the edits to be in the root, and the originals to be moved into a new subdirectory called "originals." I believe an array would allow for a user to define (as many as they need) subfolders/global folders to allow for more flexibility in organizing folders into subfolders or global target folders.

As echoed by many, would love the ability to edit/see IPTC keywords, and potentially filter/sort by these keywords.
