Alacritty doesn’t support TABs. Running a multiplexer locally doesn’t work well when you run another on your remote session. Uuuuuuugh! Nothing is ever perfect.
@bender@twtxt.net What multiplexer do you use? I usually use Tmux and have my prefix mapped to C-a on my local machine and the default C-b on the remote ones so they don’t conflict if it helps.
