Wansted to switch to an alternative terminal emulator for fun. Searched for a week and ended up using WezTerm (https://github.com/wez/wezterm/). Rust based, with enough features (tabs, splits, ...) without too many bells and whistles (GUI config, ...) . Recommended.

Alacritty is also a very nice one, specially if you want to truely understand what a terminal emulator is; under the hood.
