Hi Eugenia,

Creator of Grigora Blocks here. Yes, we have a long roadmap ahead, and hope that we deliver the best in the coming weeks. Great thanks to WPtavern for covering this.

Yes, we'll be fixing the above-mentioned errors this week. Moreover, we'll launch a first-ever ready-to-use templates import system for block themes soon (End of this month).

Regarding the screenshot, yes we can create it as it is by using "Grigora Transparent Hero" Patterns. We have not added this by default because we wanted this theme to be a direct plug and go for bloggers.

Cheers!
Pratik
