So Mathcad Prime matrices now have a new matrix navitor which gives you a free-range window into your data. Much better than sliders. This is a classic example of the new kidsn of development we can do with a new UI code base. This is just the beginning.
The Ribbons UI is here, love it or hate it .. its here, Microsoft said so. I like it .. everything one click away. I love Mathcad 15 but everythign was 2, 3 or 4 levels deep in UI. Its hard for me to go back to MC15.
I was wrong about your apathy toward bug reports. Please accept my humblest of apologies. I was wrong.
