Looks great, the only gripe I have with Kitty is how slow it is,
especially on startup. I guess mostly because the combination of
Python and tons of features has a negative effect in this area.
In fact that was the only reason I switched away from it despite
its great font ligature support; I use terminals a lot and so
the constant delay when opening a new window was a bit much.
However I like those modernised protocols and it would be neat to
have widespread support for it.
This! I would love a "purified" version of kitty which is just an xterm with font ligatures. And no silly features like underlining of links, etc. Also, an option to display bold text by using brighter colors (as God intended).
It's still an order of magnitude slower during startup than other terminals such as xterm, rxvt or even mlterm. On my intel laptop I can often see the gl context flashing before becoming the final background color, which is annoying. Requires also way more ram.
kitty is a great terminal, but it's one example of fast not being also lightweight.
