Congratulations, the new interface looks great!
I would like to make a few questions though:
Is sharing an App the only way to run it?
The dropdown edit box (at least under Chrome on Windows) will not show the options when I click on the down arrow, only when I click on the box content itself. Took me some time to figure out, is it how it's intended to work?
It also seems to loose the current configuration whenever I hit the Save button, and that makes me wonder if I have to set them all again if I make a change.
Isn't there a way of enabling the Save button only when there is a change on the controls values? That would help knowing when changes have already been submitted also.
They are all minor quirks, I'm excited about the possibilities and wished you already had more samples and widgets!
What's coming next?
