I was a fan of Alacritty and used it for the last 3 years, but I was frustrated by the lack of features
You were a fan, but didn’t realise that it’s minimal on purpose?
It’s AFAIK the only popular, minimal, GPU accelerated terminal emulator. It doesn’t have tabs, multiplexing, and other features because it’s not supposed to. Your wm/tmux handles that already, and scrollbars are waste of screen space.
Would you also complain that a flat head screwdriver is missing those cross bits to help you unscrew phillips heads?
