I've been thinking on something similar for a long time, and first of all congrats for actually building something. I never got that far.
As for feedback, I'd strongly suggest focusing on UX above all else. I tried Polarized a while ago, and gave up on using it because it didn't 'feel' very usable. I know that's vague feedback, and I wish I could be more specific, but broadly speaking it just felt more like a great idea rather than a great tool.
The internet wasn't successful because of the idea(l)s behind it. It was successful because it was simple, practically and conceptually speaking, and anyone with a text editor could do something amazing with it ("look ma, the whole world can read what I wrote!").
Or another example: I get all warm and fuzzy when I think about Emacs and its extensibility and whatnot, but I use VSCode for most of my day to day coding because it gives me a nice default set of features that are well-integrated and presented in a unified UI. I also don't particularly like Apple and what it stands for, but here I am paying a premium for a MacBook (2015 model, but still) and OSX because if I'm gonna spend my day using a tool, it better feel right!
