I have never seen Scalos in action. Can you test it and make an easy selection of either scalos or magellan? Of course, if they are comparable.
Magellan cannot show thumbnails in way ms windows does. But, i thing magellan is pretty much configurable. Can you make that, instead of opening new window which shows thumbnails, it would start program that put thumbnails into icon files?
I am pretty sure there are programs that do that kind of stuff, but i am end user that is not much into technical.
Other thing; amikit is GREAT, keep it that way! And put more videos
