Just did a new install of ATVO on fresh PC. The "Data Bindings" are very limited to what I'm use to seeing (i.e. weather missing, etc.). When I open up a previous theme they are there - but when I start a "new" one, they are not. Thoughts?

Did you select the right Data Set for your parent Widget? Weather is in the 'sessionstate' dataset, by default Widgets get the 'followed' dataset which is about driver entries and their results.
