I really want to like Kitty, but it's a very opinionated piece of software, and there's a number of decisions that just make it hard to. No GUI config is one, and I can't be arsed to go through multiple cycles of changing a config file, checking if it is alright, then going back. One particular sticking point for me, even after I got my config going, was that I couldn't resize my tiles with the mouse. This is by design: the author doesn't want it. The keyboard shortcuts for resizing tiles also don't work on an axis level, and you can only make a tile wider or narrower. Obviously, this means you can't configure your arrow keys to resize, as the mental model would break depending on which side of the screen the tile is on. I wanted Kitty because it has ligatures, tiling and GPU rendering, but after fighting with it a tonne, I just gave up and moved on.

And that's the thing about opinionated software: if you don't share the opinions it was built with, you're not going to enjoy using it at all. By all means, Kitty is amazing if you get into its model, but for a large portion of the audience I think Konsole or iTerm will just suit you much better.
