- kitten, a lot, they are useful. I will name a few. kitten ssh, keep a long lived connection so that you need to authenticated once for the whole kitty window. kitten tranfer, transfer files between remote and local when you are inside the remote host. kitten clipboard, take data on the remote host to the local clipboard.

- customize your keyboard shortcuts to be more efficient on creating new tab, moving between tab, keep the current working directory when creating new tab, split panel (even you are on the remot host).

- tune the performance configuration.

- on macOS, you can hide the title bar of the window, give more minimal look.

- take time to learn from their documentation, a lot of useful things to be known.

- the author is uncompromised on the performance, e.g. https://github.com/kovidgoyal/kitty/issues/884

- don't ask the author to change kitty icon (but you can change it yourself, I did): https://sw.kovidgoyal.net/kitty/faq/#i-do-not-like-the-kitty...
