It's hard to pick a name. All the best ones are taken or the .com isn't available or you just can't settle on one or dozens of other problems with naming. Naming is hard, as they say.
I picked Polyvars. Poly, like many. Vars, like variables. There are many variables that make up sites and apps and to change them currently takes coding and deployment. Polyvars enables people to tweak those bits with a text input and a save button.
