I do the same - largely because I open the IDE with `idea .`/`zed .` (or whatever) from a directory with the correct nix dev shell already loaded in order to ensure the correct toolchains get used.

Typically I have 3-4 different projects open at a time and probably 30-40 terminal windows across them and other places (in Ghostty).

Honestly it had never really crossed my mind that people used the built-in terminal for anything!
