I don't know if the Dev uses LLMs (EDIT: He does) but he's been very lackadaisical about security. His code is often messy or takes shortcuts (I'm not a programmer, I just read what other folks who do have programming skills have brought up with him as issues). And he's been crazy hostile in some bug reports to the point of being nasty and dismissive (including important security bugs). I don't use Kitty because it's overkill for my needs (I've recently switched from Konsole to Foot) but the lazy security is making me seriously look into alternatives to Calibre because I no longer trust having it on my machine. Do an internet search for something like Kovid Goyal hostility or security issues and you'll quickly come across discussions and bug reports demonstrating his shit attitude.

Konsole is a great terminal emulator and I used it for more then a decade (together with yakuake, which is Konsole anyway), but on my machine (8 years old Thinkpad with integrated Intel GPU) it's too slow in rendering on a 4k screen. Scrolling too fast in my nvim session makes it stutter.

Kitty (and I assume it's other accelerated brethren) is butter smooth when doing the same. I replace yakuake using a second Kitty process and a Kwin script to appear it and disappear it with F12 or another shortcut.
