1. Color background opacity slider on columns.
2. Gradient controls added to overlay filter so that one side could be more opaque than the other.

I have used it to recreate an Events site with models: Event (date, time) and Location (street, city). But I don't see anyway to create a relationship to add location to an event. Is there a way?

I take it back, it's working locally now. I am not sure what I did to clear the issue. All I did is delete that plugin, loaded the Team model that I had exported from the playground and saw that work fine. Deleted that and loaded the "Latest version" link from github - still says 0.02

I think overriding the default patterns is job one for a serious theme. Colors and even fonts are more of a style variation thing, in my opinion.
