I do not see anyway to sync changes, mods, or additions to the cloud image files.
Am I missing something or is this a needed feature? (They had it until they told GoodReader to cease).
John,
I don't think you're missing anything. The more I work with it, the more I think it is a potentially very attractive service with some crippling flaws. I suspect that the flaws are intentional. There seems to be some kind of race amongst the cloud storage suppliers aiming for the mass market – Google, Dropbox, Microsoft, and Amazon, to name a few – to see who can offer the most storage. And, just like it's hard to compete with free, it's hard to compete with unlimited. But you don't want your customers actually loading terabytes of data and your cloud center, especially when you have moderate-to-quite-expensive services aimed at commercial users. So, it's a good plan to make sure that there are just enough limitations in your free service – and, since I was already an Amazon premier customer, this new feature is free, well, included, to me – to make sure that the high-volume uses go elsewhere.
That said, I find some of the things that Amazon does allow to be pretty amazing. For example, it supports TIFF and .psd files. In addition – and this really blows my mind – it supports .psb files.
I don't know the story behind Amazon's asking Goodsync, and apparently GoodReader, to not support the service, although if part of your marketing plan would limit the utility of the service, you'd want to make sure that third parties didn't put back the features that you deliberately left out.
