Yes, I've found that the most significant improvements for me came with bash aliases, a few little scripts, and nnn for anything that has to do with folder navigation or file browsing. Its search-based navigation speed is unmatched. Another big upgrade was dmenu. Just slap it in some bash script and now it's interactive. Combined with xbindkeys you can even bind those menus to keys, and it'll work on any Xorg-based desktop.
