It would be better if on the extensions page there would be some filters on the versions of nopCommerce and features like display only free products.
Like if I click the "templates and themes" link and then click on "nopCommerce 2.30" it should show me the themes that are for v2.30 instead it shows all the products for v2.30.
Currently its relatively easy to find stuff even in this setup but when the developer's guide is released the number of extensions would increase dramatically and this would make it a nightmare to find the stuff that you want.

Thanks for suggestion!
