Animatic with blender?

Hi, I have seen in the latest blender svn some new stuff in sequencer editor to help create animatic stroyboard with blender (like separate images to strip and grab/extend mode frame) it think only two thing missing to became a good animatic creator
-load images automatically in Uv/Image Editor the same images as in Sequence editor/image preview for painting it or possible enable painting tools in Sequence Editor / Image preview.
-Automatic saving images after every painting release with more undo levels.

*Animatic = is an animated timing storyboard see the example of peach project here
