Fullscreen Info (I): For all EXIF options, add a corresponding unit. Behaviour now (example): <Focal> displays just a number. Wish: Change all common (or all easily abbreviable) tags to display with a default unit indicating the meaning of the value. This can currenty be done by manually adding the unit after a tag. However, if EXIF values are missing, you have a useless info-line just with units. I suggest to use no caps, because thats less distracting. (14mm, f/2.0, iso400 1/4000s etc.)
Image Display: Raw handling in its current state is lacking flexibility. Of course whats very nice, that I am able to use embedded raw-previews. Fast workflow, my compliments on this. But sometimes I need to look at the pictures in full res (evaluating best small detail version), and thats where I get nothing but problems. I have to be very careful where I click because I cant interrupt the raw-decoding. So, I am effectively not able to normally browse thru the pics. I suggest 2 things. First, the full size decoding should be self interupting if user navigates to another picture. Second I suggest a different rendering method, zoom dependent Raw decoding: Have a Small Size Low Quality first view, followed by a refining step for better Quality. Finally if user chooses to Zoom in, maybe after 3 Zoomsteps the full/half size version (configurable) is rendered. The user would be able to interrupt at any time with navigating to another pic. I realize however that this is MUCH work.
Image Display > Bug: While testing I also discovered that Fullscreen mode ignores "raw full size" option (seen with cr2 format) it uses the embedded view instead. This occurs only if you have XNview configured to only use the fullscreen without the regular viewer. (Priority: Low)
While at this, it would be good if the resolution indication (custom via infoline and in status bar) would always display the true resolution wich the engine is currently displaying. So that you are able to actually see wich version you are watching. Would be useful for seening with raw size option you are using. (However this is minor)
Interface: An entirely different wish, I guess probability getting this feature is very low because its too speciaized. In Canon Raw Viewer (Zoombrowser) I can have a mask over the picture, showing all AutoFocus Points, and Highlighting the AutoFocus point that was used for the picture. Please implement that, it needs to be only for Canon
Seriously, if you would implement that, I volunteer to provide you with the correct Autofocus Overlays for each Camera and each Camera Vendor you wish to implement, handdrawn, in any format you need. I think this would make XNview even more special, as I dont know any viewer (aside from the vendors own breeds) who supports that.Finally 3 small interface things,
when displaying Parent folder in Browser in Thumbnail mode, I cant reach "Parent" with PageUp Key. I know The Pos1 key does that, but its just one key more to use, wich slows me down because I have to do perform one action more. And, for making selections, I can still use the Arriow keys, so I dont see the use for 2 slightly different performing keys (Page Up and Pos1) where I have to use Pos1 only because Page Up is too strict.
Option to display directories in detail view (at the top) and at the same time the Images as thumbnails (below). Essentially possibility of mixed thumbnail + details view. The effect for me would be easier overall navigation, since I tend to focus on folder names.
Often I have corresponding raw and jpg files in the same dir, both showing the same subject but at different resolutions. When I browse these pictures, I essentially view every subject 2 times, wich is a timewaste. An option to display (configurable for browser, viewer and fullscreen) only either the jpgs or the raws would be good for this case. The best criteria would probably be the filename.
All the best
