I don't suppose there's anyway you could add support for Google Drive?
Sorry Jon, this app is no longer maintained.
The direction in which AssetCat will be developed has changed.
The next release of AssetCat will be a different app all together, and it will not require any cloud storage like Dropbox and Google Drive. However this is a major update and will be some time before any news is released.
The physic my girlfriend visits reckons it will be 1.7 years haha :P
