I tried antigravity when it was first released, I didn't see an advantage over vscode, which it's forked from, and there were a few extensions I used that aren't supported. I've been a huge fan of copilot in vscode, the tight integration beats the TUI harnesses, and I've built some tooling around it (https://www.agentkanban.io) so I've got an integrated task board, context capture on the board and git worktree management for parallel tasks)
