Ivan. This is a great plugin and just what I have been looking for. Thanks so much!
My two minor issues are the speed the download link is delivered to the customer. Sorry, I have no idea why that might be as I am not particularly wordpress savvy and it may have nothing to do with the plugin itself...just wondering.
Also, the fact that it seems you can only purchase one download at a time. Would love to encourage my buyers to buy more than one item without having to login to PayPal each time. Any plans to develop that in the future? I am currently using FatFree Cart but would love to offer instant downloads instead. :-) Thanks once again!
