We can't give dates or guaranties on new features for various reasons. It mainly depends on the development roadmap we've defined for the developer and problems we may encounter during this period
What I can say is that we are currently finishing a new version 3.4 that will include a stat dashboard, an upload form... and the next major will be the 4.0 with Dropbox. It's a long shot to integrate such component with their API, I would say 3 month at least from now.
Hi Tristan, thanks o lot for your answer... I guess what such a development can be :-) Your component already rocks ! It is just a feature needed by one of my customer... But I will wait as Dropfile is the only one component which offer such solution at least with Google drive !
