I'll take a rust tmux if it runs on Windows. I'm currently kind of stuck on Windows and I didn't realize how much tmux means to me until Bill took it away :(
Why are you stuck on Windows?
Some programs only run on Windows, this isn't a new problem. Personally, the only reason I have a Windows installation on my desktop is because Ableton doesn't run (well) via Wine, so not a lot of options really.
