#3 was more driven by my frustration with GA. It wasn't clear if GA is limited as a datasource or feature limited by free/paid tier.
I'd suggest removing GA from the site as a feature or calling out the current limitations more clearly. While I could go get data out of BigQuery, that's more of a lift and the ease of using this to import GA for clients is a major draw.
Thanks for the quick response and I'm looking forward to using it more.
