Love TUI apps, hate that there isn't a clean way to control native scrollback. It leaves you stuck between manually managing it via awkward hacks on the current visible screen, or not using it at all. I've been working on an LLM harness TUI for a little while, and this specific part has been the most frustrating (in conjunction with tmux).
I've been working on a graph database in Rust this year actually! I'd love to hear anything you can talk about wrt the query planner and/or how you decided to do cardinality estimation. I decided to go with an EAV graph which makes CE pretty complex, and it's been an interesting challenge to balance quality and speed and expressiveness in the query language
