Changing Thumbnails for Folders and Videos

Aloha! I've been using this browser for a while and wondered when a feature to change folder and video thumbnails would be implemented. The Stash app by Hedonic Software had such a feature. I understand this is purely cosmetic and may be more trouble than it's worth, but I sure would be a quality of life improvement to your browser! I'll continue to look forward to such an update for years to come.

Thx for reading!
