- quickly jump to recent directory: https://github.com/rupa/z - however I find it kinda annoying it seems to forget/ignore(?) directories, anyone know of a better version of this?

- quickly opening my personal wiki: https://github.com/francium/dotfiles/blob/master/bin/.local/...

- re-run a script when a file changes: https://github.com/francium/dotfiles/blob/master/bin/.local/...

For `while-watchdo` you, you run it like `while-watchdo "echo hi"`, then in my editor, I have a custom shortcut that does `touch .watchfile` causing the command, in this case `echo hi` to run. I prefer this to tools that retrigger commands as soon as you save _any_ file. Also works in docker containers, edit a file on host, command runs in a container.
