A lot depends on what are the important parts. It could be essentially identical if it supplies all the parts you care about and don't actually care too much what exact form it takes. But if you require the same exact gui controls then sure, totally different and not even an answer to the question.
And you have to get into tmux configs which is a hassle by itself. I am not a fan of terminal multiplexers, I tend to forget them and when the server crashes or reboot it won't replay/restart what I was doing in those tabs anyway. I just use them for long running jobs I am testing. I also don't like the whole tmux window/pane manipulation you can do, I'd rather have my primary DM to do that well.
It's funny how tmux is downvoted in those replies though :D.
How does it work in MacOS? Since some terminal commands are interactive (vim) and others have side effects (well, really, effects— rm won’t have the same result if you replay it!) I guess they can’t just be replaying/restarting programs, right?
Personally the only thing I really need is `mode-keys vi`, the rest is optional. I guess you want to configure mouse on/off depending on preference, if it differs from the default.
Usually will at least change the color of workstations and desktops just to make it more visually obvious which tmux environment I'm looking at when sshing and nesting.
It's C-b by default, C-a is what screen uses. Maybe you copied someone's config, as that remapping is fairly common (or weird distro default? but seems unlikely). I'm personally fine with the default C-b and have always kept it everywhere.
