I think this would be very helpful with Anvil.
Many apps have forms with repeating panels with row template forms using events to delete, edit and add items, etc…, and I find myself repeating similar chunks of code again and again.
I thought about creating my own cookie cutter, but there isn’t any useful enough generic starting point.
I have already given up using vim-ish editors, but this might make it worth giving it another try.
Are you letting us try on our own starting from the GitHub page or are you going to give us some step by step setup instructions? 
Does the Copilot integration sit on top of the vim (or whatever you have that takes over the editing) integration?
PS: The animation does the job of giving an idea of what’s going on, but I would have liked it on a smaller area, so the text would have been readable. Same comment on you other post.
