Editing src blocks directly in org file is nice but you cannot benefit from all minor modes that would be enabled in dedicated code edit buffer, more then that for a big babel file the performance struggles. Usually I forget to do this additional keystroke and end up editing in org. Is there any out-of-the-box option or simple workaround this can be made automatic - e.g. whenever I hit edit command the buffer is opened automatically and gets activated with all input continuing there?
p.s. I'm using evil - one thing that came to my mind was capturing some evil-into-insert-mode-hook and checking if I'm inside a src block, but this is does not cover all cases of course
