All these desktop plans, talk of "recent documents", application groups ... I sometimes wonder what kind of activity actually uses such concepts. I keep applications open; I use them to open documents. I don't double click on icons in a file manager to open them. I use virtual windows or desktops, whatever they are called, to group my activities, and just bop around with arrow keys to get there. Hot corner -- why? I dedicate some key combo to bring up menus.
I get all the flexibility I need from fvwm, and it doesn't take a lot of space or memory or attention. I am woefully out of date with these new fangled computer concepts. Pretty soon I'll be setting in my rocking chair on my porch with my M1 Garand, protecting my lawn. Only I don't have a lawn, it too takes too much care and attention. Maybe I'll just lay out some astroturf.
