The best thing in the last year was that I made a mode for my job. All of my work repos are under the same folder so the mode gets activated for any file under that folder.
It's small right now but has functionality like creating a new migration and switching to the new file. I also have yas-snippets for SQL tied to the mode. Using which-key helps me not have to remember all of the commands.

I think the command's name is where-is, not which-key.
I think they meant this package: https://github.com/justbur/emacs-which-key
