Philip Luppens commented on WW-2808:
------------------------------------

Ok, some more fun. I think I have found a rather drastic solution, but I'm investigating it a bit further to make sure I don't oversimplify it too much. 

In 2 weeks I should have something for you to test. Let me know if you're interested in evaluating it.
