- Drop targets on the desktop. 
- Sync the screen panels with the real panels
- Use containers instead of WPanels as the toplevel window displayed
- widgets event forwarding in WInputs and WPanels.
- Split view.
- Menu organization
- Intenrationalization
- All of the dialogs.

Possibly make a way to bind a toplevel widget to the Dlg_head part of the
system so that grab_add/ungrab and the widget destruction reuse all of that
code for NON_TED dialogs.
