Data Browser View Mode

When launching the Data Browser via the CSS Menu, from the context menu of a PV, or by opening an existing Data Browser configuration file, it runs in edit mode.
As the name implies, this mode allows you to edit, i.e. change the Data Browser configuration by adding PVs via Drag-and-Drop, by opening the associated Config View and Archive View.

Alternatively, one can use the context menu of a Data Browser config file or of selected PVs to open a Data Browser instance in view mode.
This is a read-only mode with limited functionality. Only changes supported by the Button Bar of the plot window are accessible, and even that Button bar is initially hidden, and needs to be opened via the context menu of the view mode window.
The only advantage: View windows offer some added positioning options, including a "detached" mode.
