You can change the clips area background to something lighter and the envelopes show up nicely, makes a big difference. preferences -> colors -> Track View -> Track View Clips Pane Background. Simple fix, helps a lot.
EDIT - and, in case anyone's missed this which it seems that some have, it really is very easy to switch between envelopes - just shift-click on the one you want to edit. I know, that's one click more than before but honestly for me the benefit outweighs the cost - I found automation really annoying to deal with before.
That said, I'm in favor of making it an option to go back to the old way, and/or other improvements up to and including a lanes-based approach. But I think it would be unfortunate to throw out the baby with the bathwater here - for me and for a number of others, the Edit Filter is a clear improvement. BUT only after I made the background light enough to see the darkened envelopes. It really helped, I hope it might help others having trouble.
