Mourning the loss of Google Docs from your app tray? (Don't, by the way - all that functionality is still in Google Drive.) Looking for something with a little more oomph to edit documents on your lunchbreak? Then you'll want to check out the latest version of QuickOffice Pro. We've covered this app before, but the sheer number of additions in version 5.5 warrants attention. You can buy the standard version in the Google Play Store for $14.99, and the tablet version for $19.99.
