As some of you good folk already know, WebAwesome, the new kid on the open-source block dropped their public beta last year. In my opinion, it’s a great alternative for Bootstrap and features some really nice components that can be easily deployed in your Hype Project!
Cool to see your integration! I definitely agree it'd be great to have the ability to support custom components and utilize them via the Insert menu . You can probably get about halfway by making items into symbols and exporting them as .symbol documents to later drop in.
That’s exactly what came to my mind when I started looking into these components. You could easily turn a progress bar into a symbol and have a project progress bar displayed on every scene and using simple javascript to grow and string the bar!
