Large Composition

I was wondering whether other people find themselves frustrated with the navigation tools built in to QC. In general I have found the built in zoom and navigation tools to be woefully inadequate and one of the biggest time sinks for me when I am editing compositions.

Some 3D modeling applications have a "Zoom Window" tool. This tool causes the workspace to zoom to a rectangular area selected by a click drag operation. When composition workspaces get huge like in the attached image this could be a great time saver as panning around gets laggy on slower machines. Another useful feature would be zoom to selection or even just making the zoom in button center on the selection instead of the window center.

If any of this is possible, KinemeCore might be the most appropriate place for it.
