Everyone knows and loves Dropbox, and with build 184.108.40.206, its Android version is about to get even better. For now it's but a preview -- a "forum build," by official Dropbox terminology -- though we'd expect that to change soon, as in my experience it seems quite stable.
The main addition here is "optimization" for Android 4.0, presumably consisting mainly of performance tweaks. Additionally, the update features:
- support for foreign languages
- quick offline access to files ("favorites")
- the ability to bulk upload photos and videos
- the option to rename files and folders
- single-tap access to all file and folder actions
- an improved gallery
- uploading from and exporting to local storage
- the obligatory bug fixes
Interested? While the update isn't yet available on the Market -- it is, again, just a preview -- it is downloadable from Dropbox's forums; if you're interested, just hit up the source link to get started.
