Why do people keep trying to reinvent tmux?

I didn’t quite understand. I use Tmux extensively and have tons of sessions running different panes etc. But how does Tmux solve the session search problem, maybe I’m not aware of some Tmux feature?

Try the left arrow in Claude Code and now you have session search. Or claude --resume, down arrow, then Ctrl-A to see everything

I know about these. My question was about Tmux. Also the Claude resume search is not full text, it only matches session names.
