RiverCross Diorama review for Digital Downloads

If you try to add more than one file (no matter how small the size, it can even be 10MB each), it will load them to the selected listing, then when you hit Save, it will think forever and never complete the operation. The only workaround is to create one main Zip file. Too basic an app. Missing tons of functionalities. I am new to Shopify and setting up my store, but so far, I am not impressed by anything here.
