Show HN: Ttmux, a Modern and Fast Tmux

Hi folks,

I recently made ttmux, a modern tmux replacement with all the things I've wanted for years:

- Modern UI with configurable window borders

- Floating windows

- Draggable and snappable panes

- Full image, color & attribute support

- Vim-like keybindings out of the box

- AI coding agent support for things like "busy" and "needs you" alerts

- Everything is configurable with an in-app UI

- Blisteringly fast (can play mpv videos inside panes)

There are all sorts of multiplexers appearing now focused on AI coding tools, but this isn't really about that. It's just the tmux I've always wanted after decades of tmux/screen usage.
