You can use any wallpaper you want but it shows as black, some skewed icons in app drawer bottom row. No other issues on Moto Z.
Good news: The folder bug does not exists for the Z!
I cannot find a more satisfying launcher in spite of its "no folder" bug.
The TSF was too much of a Hog.
I have moved on to TSF Shell. It has all the features of Xperia & more. Worth the price too.
If you create a folder it will not last. While the workaround fixes the loss of icons. Lossed folders are also a consequence of the initial bug.
In fact may be the cause of the bug.
Therefore folder creation is not allowed on any homescreen! !
Those on launcher pro plus OR nova launcher can put the xperia app drawer in place of the stock app drawer. Xperia drawer button in center, Nova button on right.
On the msm8960's, which includes the x, the launcher is marred by the Bootup condition where (sometimes) homepage icons/shortcuts are missing. A launcher/settings > restart launcher is a fix.
Dev is no longer supporting this launcher http://forum.xda-developers.com/show....php?t=2103403
