cmux — The Terminal for Multitasking is a pretty brilliant terminal program for CLI workflows, which are experiencing a resurgence especially through agentic coding. And what I love about it: it has clean persistence of open workspaces where you can have multiple tabs, so I don't have to keep my work environment open all the time. I've always liked having various directories open directly because I switch back and forth between several while programming, and this works much better with CMUX than with anything else.
