There are now controls for WinForms, WPF, and Avalonia. Controls have various configuration options, and all controls should have the same options. A Configure() method was initially created to make it easy to toggle things like panning and zooming, but it has grown so large it is now totally ridiculous.

Create a ControlConfiguration class, and modify every control to have one of these objects at its top level. Users can then modify its pubic properties directly (rather than calling a large method with many optional arguments). The old Configure() method can stay, but be marked as obsolete.
