Google has released an updated version of Gmail for Android that includes a new "All Inboxes" option which does exactly what it sounds like; offers all of your inboxes in one spot.
Even if you have inboxes from Outlook or Yahoo, Gmail for Android will display them, and you'll be able to read and reply to each e-mail, without swapping tabs or logging out. The Mountain View-based search giant has also teased that e-mail threads from external accounts will now be displayed with the same threaded conversation format that internal Gmail e-mails use.
The new integrated accounts will also make use of the improved autocomplete function, larger attachment previews and one-touch saves to your Google Drive account.
