Clearcanvas plugin

We would like a plugin developed for Clearcanvas, specifically the viewer (client side) of the application. We would like a plugin designed so that the user has the ability to choose and select hotkeys or keyboard shortcuts which will determine the image layout or tile layout (e.g. 1x1, 2x2, 3x5, 4x4...). The plugins for this software are typically established into 2 files. One .DLL file which is stored in the plugins folder, and an XML file which is stored in the main clearcanvas folder.
