If you haven't used Superhuman, it's an email client with a ton of amazing key strokes. You can fly through email with the tool.
I'm thinking that Sublime Text could use a re-think like this.
Sounds like vim keybindings?
I'm a fan of TabNine et al which try to do more sophisticated autocompletion for a faster & more magical experience
Yeah exactly!
A bit more 'magical' than TabNine in the sense where highlighting text should auto-display instances of that text. If it's a function name, it will show snippets of files where that is used.
Eventually.. in-line code evaluation and really nice keyboard shortcuts for all the other common tasks like display as markdown, snippet generation, indent formatting, etc.
The list goes on and on and on...
If you look up "best sublime packages" then you'll get a sense of all the capabilities that make the dev experience really nice.
Packaging all that up into very easy to use keyboard shortcuts in a Superhuman-like way
