I think part of my resistance initially was that it took up much screen space with borders and such. I learned now that that can be switched off or modified. Didn't go deep yet, just tried the different options from `zellij -l welcome`. I think that should actually be the default startup and then maybe disable or prompt to disable in future.
has some starting links, if screencasts do it for you
For me the only glitch was some key binding collision with ghostty/aerospace but it works perfectly out of the box on alacritty for me
