TreeView Wrap and Subwindows in Tray

Dear fellow Vaadin developers

After a few weeks of development I have run into a few issues that I’m hoping you guys (and gals) can help me with.

  1. Is there a way to wrap the contents of a tree into multiline so that my HorizontalSplitPanel doesn’t scroll horizontally?
  2. Is there a way to put subWindows in the tray area where they stack ontop of one and another (like lets say, notifications but that the user needs to interact with them)

Hope you can help me with this!
