Just a tip - if you'd like to use vim on ChromeOS - look into Caret. Its a nice code and text editor like Notepad++, and it has a vim-mode. Its been a while since I've used it, and I don't think it's very extensible, but its something.
Zed[1] is probably the best editor on Windows, OSX, and Linux too. I hate to go back to editors where I have to save, manage what tabs are open, and clutter the workspace with toolbars and buttons.
