Dropbox fans, you're in luck – version 3.0.0 is completely redesigned to follow Google's Material Design guidelines.
The new app, which can be downloaded from APKMirror (click here) but doesn't seem to be live in the Play Store just yet, includes all the goodness Android users have come to expect from Material apps – a FAB (floating action button), flat UI colors (i.e. no gradients), a slide out hamburger-style menu with authentic motion, it's all there.
We'll update this post if we notice anything else major.
