Hi, Kevin asked for developers opinions on this issue, just thought I'd leave my own.
Didn't have time to read the thread thoroughly enough, don't have much time at the moment to do it. Apologies for that. Just wanted to make a comment about the CSS support for this feature. I think if you add it, it would be great if it follows the CSS web spec or at least it doesn't go against it. I think there's a lot of value if we start more and more following the web css spec, it would mean a web designer could eventually transfer his skills directly to javafx or that we could use tools used in the web or that we could simply copy paste a CSS web example into JavaFX and it would just work (though we're still a bit far from that but could be a possibility in the future). There are a good deal of big companies already involved in developing web css, I'm sure they've put a lot of thought into it (not speaking of the early days of CSS which was very bad).
