Hi Stephan;

      I have already highlighted to the Appeon engineering team the need to control what docked window options are shown, set the language text of the dropdown (multi-lingual Apps), restrict the user's movement options and get notified when the user changes the document type and/or location. As you may have guessed, these options are not currently implemented in Sybase's Dockable Window feature that was added in PB 12.6. The same implementation and behaviour is also now in  PB 2017 as Appeon PB is built on the PB 12.6 Classic code line.

    I would like to suggest that you  open a Support Ticket as an enhancement request for these features to be added / modified.

Regards ... Chris
