by these definitions it is also a very "minor" fork
as "minor" as it can be :) not that I don't think this is ain't nice
as all of the changes are basically contained in a few open PRs for vanilla (except for the logo).
But what's your plan with it? Keep it going and add more stuff even if most of the PRs get into Vanilla? I think the one that allows us to write color themes plugins has a good chance to get in, and it's one of the main selling points of your fork.
