I'm not sure I really understand this. I mean I understand the goal, but do we not have that without the manager piece?
So like I have a folder called AppImages. I right-click properties allow exec. I make a menu launcher.
I can now move that folder to a new PC, and ... Maybe this is where it shines?... I don't have to right click on each and I don't have to make launchets for each (or clone the menu folder i guess).
Or does it like ... Check for newer versions or something? What am I missing?
I strongly prefer AppImages for a number of reasons so I'm all about having something useful for them.
