Wezterm is actually programmable. I am looking to drop Kitty as it intentionally offers minimal tmux support and the text rendering options that made it superior for me are being deprecated.

Until Ghostty offers the scriptability found in wezterm and kitty (e.g., hit a keybind, spawn a new terminal and execute a font picker script), I am trying out wezterm, which is pretty great, but renders fonts too thin by default. I stare at this thing eight hours a day so text rendering is super important.
