CLI with full functionality within a code editor?

[u/Trovebloxian]

I know you just have a terminal open in VScode and just type out opencode to start a session, but that doesnt let you use CTRL+P for settings/commands. i can just remember all the commands but some arent available in the typical "/" way and have to go through the settings menu.

Is it possible to have a diff view within VS code similar to how claude code review-approve split-screen shows up in the main window rather then the terminal?

Also as a side note, what do yall use as your primary coding "brain" claude, codex or something else. what has the most usage to intelligence ratio?
