I decided I didn't like where betterCanvas was going when they rewrote it and added accounts and subscriptions, so I went to their github, reverted to the MIT license so they can't do anything about it, and added more features.

I want this to be the FOSS version of the current extension, so nobody has to keep being pushed to make an account or pay to make their canvas look better.
