I think that unfortunately that Google is pulling the last ventilator support from beloved old matrix. It takes upto 10 seconds for any parameter to resolve..for eks sales city, currency src, destination pairs etc. Plus it's impossible to search for any side trip on old matrix anymore. It shows no results found contra to results shown on new matrix.

What a pity. I just hope that the new matrix GUI is optimized to be effective and efficient as the old one. The new GUI is almost all over the place and counter intuitive unlike other Google products.
