> free-form "rectangles and text" building blocks

As a backend dev, I find that the most annoying part. I don't want free-form; I want something I can put together in a few minutes without having to think about design and it still having it look acceptable on the platform I deploy it on. On the web I can do that with bootstrap (and it's 100.000s of themes), native I can do this with the native libraries but in the html5-for-desktop-apps space it seems I have to spend time on doing stuff I don't want to do or even care about to make it look anything different than vomit; that is simply not worth the time. I know that is very different from your use-case, so not saying you are wrong or anything, just that this is what annoys me about html/css. I think there would be a market for 'electron desktop themes' like (1) (basically unsupported now) but seems there is not (or no-one finds it necessary anyway; maybe i'm the only one with this 'issue', well, me and all my colleagues that is).
