It appears that Dropbox is also tweaking its Android app to better suit the Nexus 7 and Jelly Bean. The cloud storage outfit made a recent build (184.108.40.206 to be exact) of its mobile software available for download as a sneak preview of sorts. A few fortunate subscribers got first dibs, but you can grab a look for yourself at the improvements. The tweaks include video thumbnails, improved video playback on both ICS and Jelly Bean, a Nexus 7-friendly UI and the ability to open Dropbox files directly from other applications.
