Yea, my first association was stool -> poo.

I've been trying to think of what other meaning they could have gone for but got nothing. Stoo lap? Sto olap?

Another voice basically begging them to change the name here, yeah. It might be quite interesting as a tool, but please...

they are even highlighting a in green after stool to break the word into stool.

i am guessing its a joke?
