Currently, there is no method to use a graphical user interface to set certain Binding Paths related to the DragDrop Noesis extension.

The current system requires creators to manually type in Paths such as 'noesis:DragDrop.IsOverlayCompatible' or 'noesis:DragDrop:IsDropCompatible', and others.

However, there are two issues with this system:

1) Knowing what to type requires arcane knowledge, or external documentation.
2) All known preset values should be selectable from a list, as we do for all other Binding Paths for example.

Therefore, these extensions should be available to searched, and selected from the Binding Path Selector interface similarly to all other Binding Paths.

Note: Image attached showing how this could potentially be displayed. See comments in bottom of ticket.

Repro Steps:

1) Download and open the attached TestFinalOK_3.zip file, and open the included 'DirectorsCut.noesis' Project in Studio.

2) Once inside of the Project, open the Collections.xaml Page

3) With Collections.xaml open, right-click on the Listbox, and from the context menu, select 'Templates'-->'Item'-->'Edit Current'
This will open the ListBox Item Template in the Inline Template Dummy Editor.

4) With the ListBoxItem Template open, navigate to the Interactivity/Triggers Panel, and select any of the 3 DataTriggers present.

5) With a DataTrigger selected, expand the 'Binding' Property.
Observe how in the 'Path' Property, there is a hand-typed '(NoesisGUIExtensions.DragDrop.IsOverlayCompatible)' string.

6) Click on the button to the right of the Path's Value Field to reveal the Path Selector.

Observe how the '(NoesisGUIExtensions.DragDrop.IsOverlayCompatible)' Path written in the field doesn't correspond to any Path available in the Path Listing.

Expected Results: All known/available Path values can be selected from the Path Listing.
