I agree. I am an enthusiastic fan of the Kitty terminal emulator [1], another of his creatures, and I am following its development (though I never managed to contribute with some code). Kovid's answers on the GitHub forum are often short and sound a bit harsh sometimes, yet he's ready to accept others' suggestions and stand corrected when needed.
If only there were more coders like him!
