I've used Synergy for quite some time, and consider it well worth the registration fee. The only feature I'd *really* like to see is the ability to see which song is next on the playlist. Overall, though, I think it's the best menubar controller for iTunes.

That said, I have NO idea what Synergy Advance is supposed to do. Wincent's page for it has a lot of grand promises, but no detail. When you jump to his roadmap page for this app, the gist of of the page is "description forthcoming."

Wincent, I really don't think you're going to have a lot of people downloading, let alone paying for, a product that has no clear description or stated purpose. Please consider also that you're effectively asking your customers to install this mysterious app on top of a brand-new version of OS X. That's a serious disincentive.

Please fill in the details. What will Synergy Advance do above and beyond Synergy? Can we pay for the promised modules a la carte, or do have to pay one flat price? What sort of upgrade price can registered users expect?

Hoping to see the light soon...
