I think it would be great to have filters available for the marketplace much as they are for the gallery.

For example:  I know I'm never going to buy a 2d background package.  Nevertheless, there are 300 new background packs everyday I have to climb over to get to actual 3d items.  Would love to filter those out completely.

And I'm sure someone else might want to filter out character packs, etc.

It would make finding what you want to buy easier.
