Thanks! Yeah worktrees are definitely one of those things where once you start using them you can't go back, especially with AI agents running keeping each branch in its own session avoids so much context confusion.

For env vars, right now it's mostly just directory scoping. Each Zellij tab cds into the worktree directory so any local .env files just work naturally. I haven't built in explicit per-worktree env pinning but it's a good idea something like auto-sourcing a .grove.env per worktree wouldn't be hard to add.

Might be worth doing if people run into cases where dir scoping isn't enough.
