The only other thing I want is a hotkey dropdown terminal, not the end of the world. One feature I miss is profiles, but you can always have multiple config files (author made the interesting choice of using Lua rather than ini/toml/yaml/json for the config file).
Has GPU acceleration, built in multiplexer (tabs and splits), ligature support, built in imgcat support, background images, transparency, shell integration, almost everything one could want. My current picks for my favorite Linux iTerm2 replacements are, in no particular order: Wezterm
While I in general prefer GTK applications in terminal emulators the reigning champ Qt is being overtaken not by them but by projects eschewing traditional GUI toolkits entirely!
