XnView Software

I have an iPhone which generates .HEIC file, after searching extensively the only software I found that can view .HEIC files is XnView.
If you could implement these suggestions, it'd be awesome.
Thanks!
PS: some are bugs

- Option to start XnView with "Show files in subfolders" already enabled.
- Opening a .heic file from File Explorer with XnView just opens XnView in browser mode, not in view mode.
- Add a close button to toolbar in Viewer (not currently available in the toolbar editor).
- Option to sort by file creation date, and clarify the current "Date" option is just the date modified.
- Allow backspace to close the viewer.
- Make clicking the "Zoom 100%" button a 2nd time perform a fit image to window.
- Add ability to add new toolbar buttons (currently can only modify/delete existing buttons).
- Show folder names (with View As Thumbnails only folders are unidentifiable).
- Convert the program to x64 for faster performance (maybe would help speed up high-quality zooms, which are very slow).

You can add new buttons

- Show folder names (with View As Thumbnails only folders are unidentifiable).

What do you means?

Only XnView MP exists in x64bits

XnView MP is 64bits but the HEIC plugin doesn't work on it...

If I set to show "thumbnails" only, without labels, folders are displayed without names

you have the 64bits version

right, but where name can be written?

There could be an option to show as "Thumbnails & Labels only for folders"
Thanks for you time.
