I hope my question makes sense.

I am using Doom Emacs for a while now and have become fairly proficient. But I feel like whenever I am browsing emacs content online there are still many topics for me to discover. So I was wondering if there is anything that I might be “missing” yet which might help with my productivity or improve my development skills.

Sofar I what have learned, on top from my head:

• Org/Org Agenda (refile etc.)
• Magit
• Vterm
• LSP Commands
• Multiple Cursors
• Literal Config
• Navigating Emacs itself (which key, debugging, reading Emacs-Lisp (abit))
• Using Language specific commands, i.e. send buffer to repl
• Using Undo with Vundo

Only thing I know that I still need to learn is beeing more proficient with vim keybindings, but with that I know where to start.

I know the question is quite broad, but maybe there some “killer features” worth to explore which I am not aware of yet.

I’d appreciate any input.
