Thumbnail building suggestion

[WhoIsRich]

Greetings.

I have a folder which only contains videos and subfolders with more videos, which made me notice:

- Because folders are by default put at the top of the file list, XnViewMP will spend time scanning all the subfolders first before it builds thumbnails for contents of the folder you are viewing. Would it be possible to change the priority, so files are thumbnailed first, then subfolders?

- The thumbnail for a subfolder skips video files and only uses images. If a subfolder only contains video, it will have an empty thumbnail, even though when opening that subfolder all the video content have a thumbnail.

Apologies if this has been already posted, I tried to search the forum, but 'thumbnail' is blocked as 'too common'.
