TIL Kitty terminal can show a dock panel on Linux desktops!

On one hand, kitty is doing a very aggressive job of advancing the terminal world.

• Providing protocol extensions to permit terminal software to use more modifier keys than were available in the past, which is something that I really wanted to see.
• Providing a newer graphics protocol than the ancient Sixel --- which kitty also supports. Terminal software can render images --- mpv can even (slowly) play movies in-terminal using said protocol.
• It can leverage the GPU for acceleration.

On the other hand, it's got some things that I don't like:

• By default, it phones home. I really do not like software doing this.
• It keeps attracting new functionality at a very rapid rate, much of which is on by default, and many of which I don't know if I want. There are a bunch of modules ("kittens"), and a lot of functionality (including aiming to be tmux-like) that I don't know if I want in a virtual terminal program. This increases the attack surface, which is something I'm kind of sensitive about for a program that's intended to sandbox content from remote systems. xterm has a lot of cruft related to older protocols and features too, but at least that's pretty mature code...and it still has had a bit of a security history.
• The startup time isn't great. urxvt can run a daemon, urxvtd. foot just starts up quickly on its own. Kitty can do kitty -1, which makes subsequent windows open quickly, but close all open terminal windows, and you're back to the window taking a noticeable amount of time to come up.
• I'm not sure about the merits of another extension, its ability to render differently-sized fonts in-terminal. That seems like it might fragment terminal software into being able to run on a grid-based set of characters and not.

I spent a while using it and then went back to foot. There's just very little that I actually want to do and would take advantage of that foot can't do (though to be fair, I might make more use of the graphics protocol if tmux supported it --- the closest one can get graphics-wise there is a non-mainline tmux fork with experimental Sixel support).

If tmux supported the kitty graphics protocol and then some emacs packages also added support --- a lot of those have the ability to use graphics, but will only do so in a non-terminal environment --- that could take me back to kitty, though.
