Actually, using Org mode and the Hyperbole package in Emacs solves all the problems listed in easy to use ways except you get much more editing dunctionality rather than just the features requested. Don’t reinvent the wheel; just learn something that runs everywhere and solves your problems. You start Emacs once and then rapidly edit files from the command-line by calling emacsclient, not restarting Emacs.

Emacs is a great software ecosystem, with a very.flexible editor built in.

With evil-mode, there's no excuse not to try it even if you find Vim's way of controlling input superior (which it as well may be).
