Is there a way to communicate that to users better? I don't think a lot of devs understand that it's easier to build up on a flat button as opposed to trying to overwrite stylesheets on a gradient button. Maybe something in the features for the final release that helps developers understand that it's not flat for flat design, it's flat because it's easier to build on top of.
True, we could be louder about that. I'll get a tweet out about it shortly. To be honest I totally forgot about even mentioning it anywhere but in a few @ replies and issues on GitHub.
