You posted in the " Bugs & Feature Suggestions" section so you're in the right place!
From what I know, work in progress:
1) XWidget 2.0
viewforum.php?f=22) New version of XWidget Android app and a new Android XWLauncher that will support java script.
Now for the dock, there a LOT dock widgets for XWidget that you can find. Now if you mean dock functions like minimize windows on dock and similar advanced functions, I don't now for the future, but for now I think that you should search for other program like Rocketdock or ObjectDock.
But you can always use all of them! All the XWidget programs are known for the low resources and these dock programs run great even on old systems.
