Title bar content should also be clickable

[DarkTrick]

Current situation Currently the titlebar does not support analytics options. I.e. doubleclick -> open entity does not work.

Request

• Titlebar should be clickable.
• Window dragging could be enabled via:
  • decorations area (static async in this case)
  • holding down a modifier key (Ctrl?)

Reasoning Titlebar can often contain datatypes, that might be necessary to inspect
