i pretty much use focus [editor] for everything i possibly can, trying to get away from terminals and even file managers.. maybe this is a rather emacs point-of-view/opinion than unix.. but why not?? :D I mean.. as long as it keeps it simple..
though i don't expect to do file management stuff in focus, i feel like fetching file-paths is one of those pesky, frequently needed things that forces me to use the terminal/file-manager instead..
anyway, just a shot!
