If by "Ultra", you're referring to the Google AI Ultra plan, then I just want to let you know that it doesn't actually take Google AI plans into consideration. It seems like the product will have its own separate subscription. At the moment, everyone is on the same free plan until they finalize their subscription pricing/model (https://antigravity.google/docs/plans).
On a separate note, I think the UX is excellent and the output I've been getting so far are really good. It really does feel like AI-native development. I know asking for a more integrated issue-tracking experience might be expanding the scope too much but that's really the biggest missing feature right now. That and, I don't like the fact that the "Review Changes" doesn't work if you're asking it to modify reports that are not in the current workspace that's open.
