Improved cart plugin
The current cart is a start, but coming from Squarespace I had greater freedom. If it was possible to include a true cart experience, get information on customers to create a use DB for mailings.
Allow shipping and inventory of stock if customer requests a print, allow for different pricing structures for example download, download unlimited license or single use. Include options on a page about frames or canvas etc. 500px has a similar model but if we could improve on this platform I believe Koken would gain the edge on the other competition!
