I remember when I was using JetBrains IDE they had this feature that would list all shortcuts and IDE features and how frequently I use them. This was excellent for feature discovery. I would regularly check it out and scroll to the list of features I never used and try them.
I always wanted the same for Vim, zsh, etc.
Do they still do this? I'm using PyCharm daily but have never seen it. Would indeed be pretty cool!
Ha! I just checked it out (had to install IntelliJ for this!) and it is still there!!! "Help" -> "My productivity".
It is probably this plugin https://github.com/halirutan/IntelliJ-Key-Promoter-X
