Dropbox is like one of those things that I want to have on the device, but don't notice it until I need it. Bah... I'd love to see a new/refined sharing plugin to address it.

Though I would say, if we were going at improving DB integration, I'd offer the additional following features:
- make a generic plugin much like the ExtraAccounts does for IMs so that DB, Box, etc.
- limited DB sync, at max 4hr intervals, files not folders
- sync/share confirmations using Notifications API

I have a personal wish of doing something IFTTT-like on device that uses RSS/XML and DB... sucks that such a feature is no longer natively available to play with. Almost makes me wanna go BB10
