It'd be cool if the Timeline had a graph of shaders with keying in use, and along the timeline "blips" that could be used as shortcuts to the shader, and tab (and frame), that keying coincides with for quick editing.
It would at least make animation management a little better than just a frame number on a slider and navigating a large network.
Maybe the lines the "blips" sit on could be colour coded with the shader groups they represent. Terrain (green), Shaders (Red), Objects (Gray), functions (Blue), etc
