C-b is less ergonomic than C-a that is the default on GNU screen. The first thing in tmux is to remap to C-a. (Triply so if you remap caps lock to ctrl.)
On reboot it remembers my tabs and panels and even commands that ran inside last (i.e there is popup in every panel that had something runing to run it again or just open a terminal)
Before my great wayland migration I ran patched st and it was great. Terminal job is render what terminal multi-plexer gives it and passes input to multiplexer.
