@beka_valentine Would something like KRunner or the command thing in GNOME or Pop OS work? I use them extensively for math, accessing files, task switching. I think most distros come with ways to customize what you can do in there too.

@beka_valentine Out of curiousity which distro and desktop environment are you running at the moment? I'm on KDE Plasma via steam OS and the krunner integration there has been pretty handy. Especially how previous results get shown first.
