Just got the update and the new features section appears to be talking about improvements made to the app for Kitkat 4.4.
This app is still useless until it allows excluding folders and file types. QuickPic is 100x better.
Hmm.. This is interesting
Source: Xperia Z Android KitKat update arriving early...
If the 'Album' update came with KitKat support, then something good is arriving, don't you think guys?
