Within minutes I ran into a problem: tried to select a theme using 'kitten themes', could navigate themes but enter did not work, nor was I able to Ctrl-C. I had to kill the app from a different terminal (ahem).

That's what I remember from trying other terminals: they usually try to do too much, and there are plenty of rough edges, which results in me having to spend too much time fussing around. Ghostty gets this right: things work well, the defaults are good, and things that you want to change are easy to change.
