Stop tab-hunting your agents!
Ctrl+Opt+ J - a jumplist pops up and you see all running agents in a jumplist, and which ones need your attention.
Ths works over cursor, claude code, opencode, codex, pi and more. It also has a mobile app that can work as a jumpbox.

It's early and open source. I'd love feedback - especially: is the phone view actually useful or a gimmick, and what agent/workflow should I support next?
