A lot of software projects have names ranging from silly associations to very cheesy puns, and IMO this should never discourage anyone - everyone should have some whimsy when naming things, because it makes names more memorable. After all, people use Python, and name doesn't even refer to snakes!

I personally wouldn't be able to remember "kitty" if it was named "featureful-python-terminal-emulator", and I certainly wouldn't want to recommend it to others under this name
