Sean McGinnis, why have you forsaken us?

So quite a few of us forum-goers use the signature generator created by one Sean W. McGinnis:

At least, I assume his name is Sean W. McGinnis, since that's the URL. :) I don't know what his in-game or forum name might be.

But anyway this is an awesome sig generator that a lot of people used to use, and I think quite a few still do. I use it to track my prestige progress and showcase my awesome roster.

BUT woe is me, it hasn't been updated since before the American Dream costume hit the game!!! It's missing heroes and team-ups as well as costumes.

So my questions are:

1. Is it ever going to be updated? and
2. If not, what's a comparable sig generator tool we can use, instead?
