Just some somewhat-constructive feedback: It's always a pet peeve of mine to see the default bootstrap theme on new web apps. It doesn't take a lot of effort to customize it and doing so goes a long way to provide a sense of authority about your application.

I know it doesn't seem like that big of a deal (and for all I know, I could be alone with this sentiment) but it makes a world of difference for me.

That being said -- this looks awesome and I look forward to getting some consulting work to try it out.
