Best Launcher ever! Xperia 206b & a workatound fix. No root needed.
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.
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.
I found an easy workaround:
Set xperia to boot with the max 30 sec delay (shorter may work too).
Dev is no longer supporting this launcher
I am Maxx'ed, X + 1/2
