The Tumblr for Android application has just received a major update. This is version 3.2.0 which includes a revamped user interface and support for tablets.
Thus in Tumblr 3.2.0 you can now find a new screen where you will find all the people you follow and from which you can look for some in particular. You now have a dedicated on screen button notifications larger instead of the combined panel with the phone.
Although Tumblr has included support for tablets, the app only works in portrait mode, which sometimes tends to be quite uncomfortable.
