What are some tiny, lightweight apps for Linux that are really neat? - eviltoast

Playing around with PeppermintOS on a "new " old laptop, and having fun. Its making me realize that tiny things can really work to impress. (Especially when you’re waiting on a ram upgrade, haha!)

Could be terminal based or GUI, I’m just curious—what tiny apps do you use that you think are neat? Things that don’t take up much storage or memory.
