Resolved Issues: * My drawing cleanup commit the other day broke shapekey keyframe selection - was using wrong filter for Action Editor data * Removed the old hack to limit vertical scrolling so that shapekeys were visible. It wasn't really needed anymore, and was causing problems with HomeKey. Unresolved Issues: * Vertical placement of sliders is slightly off * In a test file I obtained, shapekey sliders don't work immediately after the file is loaded.
