Is there a list of MarketPress addons somewhere?

I just spent ages trying to find some of the addons I've already found for MarketPress (floating cart, for example) and looking for others that work with it (Ultimate Branding, for example)... but I can't find them.

Is there a list of plugins and stuff somewhere, or do I have to trawl through all the product-specific pages and blog posts in the hopes of spotting something useful?

Thanks!
