I often install some apps and forget them later… So I have many apps installed that I don’t use but that take a lot of disk space. Since I’m using KRunner to open apps, I rarely see that apps somehere. I think it would be good, if there was a section “Unused apps” in Discover or any other place in the system.
the app menu has a drawer for recently used or most used.
it would seem like the logical place to also have earlier used or least used.
tho simply perusing the app menu categories to find apps you don’t use any more should be fairly easy, then you can just remove them via discover or the command line.
