See my setup detailed in another sibling comment of yours, jj is just a small part of it, and you can probably get that with git too.
I’m already at full mental capacity planning and reviewing the work of two agents (one foreground which almost never asks for approval, and one background which never asks for approval).
I don’t really need the ability to juggle more of them, and noticing their messages is not a bottleneck for me, while I’m happy with the customizability and adaptability of my raw’er workflow.
Maybe if they’re as slow as codex…
