Some things that I noticed that could be improved.
Definitely need the net highlighting as found in the classical Express PCB. It's nearly impossible to lay out a sophisticated board correctly without it.
Also need the key shortcut ("L" in the classical version) to switch between layers when laying a trace.
There's an issue with selecting the text on a component for moving it. Most of the time, if I select just the text I end up moving the entire pad (Classical version worked fine). I have to double click, hit the button to rotate the text a few times, and then I can move it.
It would be best if - as with the Classical version - we could actually see the pours for the power and ground planes. This allows visual verification that we have the proper thermal/solid connections on a via.
Both versions of the software have issues with one-pin parts (e.g. test points). It won't "group" to make a part unless there's more than one pad.
