As others have s pointed out, it looks like as a relatively new user you’ve tried a whole lot of stuff meant for advanced users and managed to completely avoid the tried and trusted Linux mainstays that have been around forever. Like KDE, Gnome, xfce, and most user friendly distros like Linux mint.

Tiling WMs for example are best for people who want to spend weeks if not months working in their configs and dot files, and are privately designed for keyboard and not mouse use (hence the WM you identified as not having a button to close the window)

But I’m curious for you end up doing these things as a new user. Is there a lot of bad advice going on out there?

I was putting it out there as a suggestion for inexperienced Linux users to manage their appimages. Writing a desktop file won’t update your appimages or handily install them in a consistent location.

I believe if we imagine a Venn diagram, users of this software would have some overlap with users who’d prefer or require a gui tool.

Years ago. I thought it had been abandoned but I see it started getting updates again last year.

No comment on the software because I have no use case for it, just wanted to note that GearLever can “install”, and integrate your appimages into your menu quick and easy, and in most cases keep them updated too.
