First of all let me say that Ultra Photo Gallery is the BEST photo album tool!
The others are way to clunky.

And I think with your upcoming features it will be even better.

It would be AWESOME to have an "optional" feature that allows for Shutterfly's Click-for-Prints integration. Where anyone viewing pictures in your album could click a button and order prints of that photo (in a separate window).

That's one of the neat features of a PHP based gallery tool - http://gallery.menalto.com/

They've also got some other nice features that would be nice to "borrow".
