Category Tree Control Optimisation

1) It would be an advantage to be able to search in the category tree like in other areas, for example the result list. For clients with many organizational units this contributes to the overview and increases the usability. (Mockup)

2) Additional button or key combination to expand all options and collapse all options

3) Additional function to navigate directly to the first found entry in the category tree control (i.e logged in user, other setting in control)
