Hello there, absolutely LOVING the recent updates. So much potential is being unlocked and I feel like a kid in a candy shop with $1,000 bucks in my pocket.
That being said, however, I think there may be a bug in how the tab items handle Element CSS. The element CSS works fine from the parent Tabs element itself, but any CSS I enter into the Element CSS on the individual Tab Items is not seeming to be rendered at all—whether using the $el selector or any other selectors at all.
For instance, I tried entering p { background-color: red !important; } into the Element CSS for an individual tab element (which should have messed a lot up on my particular page), but it did absolutely nothing to the page at all, which tells me something may be unplugged somewhere for this field. Actually, this afternoon, I was cooking hot dogs for my kids in the convection oven before I realized the mechanical timer may have been winding down, but it wasn’t plugged in. Yeah, kind of like that. 
I could be wrong, but it might be something to look into.
