@tauren I'm not sure about style generators. What's an example? I typically use chrome to tweak styles like you're saying. But as far as tweaking inputs in realtime, I've been using dat-gui for that lately! These are all more manual approaches though.
@tauren hmm, who is your target user? web component consumers? seems like a good idea.
@treshugart do you have an idea of how/where the webcomponent polyfills do feature detection? i'm having trouble with the skatejs webcomponent shim in that it doesn't work on a couple chromium based mobile browsers, but i haven't really dug in yet
