Realistically, what I use about its agent stuff is:

- reliable notification pings either via what your terminal app uses (e.g., ghostty's) or system or just within herdr only

- if absolutely necessary, be able to tell agent sessions to observe and run commands on a herdr pane (security beware, for obvious reasons)

- herdr --remote which is basically a quick SSH -> attach to herdr on a remote

- prefix+g (equivalent to prefix+w in tmux) presents itself nicer, has binds for agent state filtering and its /search imho is mildly nicer than tmux's

Arguably, you can have the same points in others if you know how to configure tmux or zellij already, so if you're comfortable with that then you really don't have to use herdr.
