I need a product.
It's like Evernote, but with the interface of sublime.
It syncs my notes automatically, and gives me a diff when there is conflict.
Lots of hotkeys for fast typing, and switching between tabs.
Better yet, with a complete history like git.
I'll pay $30/year for this service.
That looks extremely similar to http://www.notebooksapp.com. Is that the same app sold differently? I use notebooks app and am happy with it, always wanted a simple interface to my text/markdown files. But Quiver seems to have a few more options.
I currently use Quiver and save my notes to a google drive account. It gives me a similar workflow to what you're looking for, sans the ability to diff changes (unless I manually commit).
Neat idea, but I'm afraid it may interfere with certain type of documents. I want it to be versatile first. Probably different modes? like normal text, auto text, ext.
Onenote will give you a diff. And it has some hotkeys. It's a good program, but in its core it is made to be used with a mouse - so it might not be what you are looking for.
