WezTerm is an absolute joy to use: Scriptable (in Lua), allows creating your own shortcuts, has a command palette, has something like tmux (called mux) for which I have created lua scripts to setup my workspace for different projects. Something like tmuxinator impelemented in WezTerm. - I still use tmux, but mux is nice as well, and I can use splits and navigation natively in WezTerm, no need for prefix-{command} like in tmux. But can have workspaces in WezTerm.

It allows adding a custom background image, also transparent background, and I can toggle all of that via my custom shortcuts: Transparent on/off, background image on/off/rotate randomly.

It is such a joy to use and so beautiful. That plus neovim, yazi file browser, and lazygit: Dreamteam. Best dev environment I ever had.
