Ghostty is a great terminal app. I've been using it a lot over the past few years. When I started using Claude Code the tabs were not enough and so I looked for a multiplexer. I did not like tmux and other apps needed better UX design. So I made Batty using the Ghostty library and I think you'll enjoy using it. It has themes, keyboard shortcuts for everything, drag & drop to move window panes and fast navigation as well as notifications for terminal BELs.
