Option to disable the "Minimize"-Ribbon Button & Behavior

[robertmuehsig]

In our application we would like to disable/hide the "Minimize"-Button from the ribbon.

The ribbon should not be "minimized" at all, so currently we do this via the VisualTreeHelper and search for the "PART_MinimizeButton" and disable it.
To prevent the minimizing via Mouse-Double click we have a EventHandler and just set "IsMinimized=false". It is a bit dirty, but works.

Would you accept a PR with a property like "CanMinimizeRibbon="False", which disables the "default"-ribbon behavior?

I would.
Please name it "CanMinimize".
There are quite a few places that enable minimizing.
The ones I found so far:

• MenuItem from ContextMenu
• Keyboard shortcut (SHIFT + F1)
• Button

You would have to modify Ribbon and RibbonTabControl and I guess you want to change the visibility of the MenuItem in the ContextMenu and the button itself based on the value of CanMinimize.
