I use Brackets.io. Best code editor out there - minimal and you can extend with extensions for the functionality that you need (automate if you will, without having to use Grunt/Gulp or whatever).

I use that exact keyboard. Yes, as you mentioned some keys are annoyingly missing but it is beautifully lightweight and nice to look at. Sometimes I feel it is a little to tight and I wish my arms were wider apart, I ache after a few hours, so I think keyboardio has something there. Pros and cons.
