What are the X symbols in a board layout file?

I'm viewing a board layout file in Mentor PADS and there are X symbols all over the board. I'm not sure what they indicate, but they don't seem to be a part of any layer and I can't hide them. I'd at least like to know what they are, but also…

xcircuit: make user defined object (hit m key) doesn't give a pop-up dialog like the docs say

I'm using xcircuit v3.10 rev 12 on arch linux. When I draw a new object and press the m key (or select edit-> make user object) the docs say I should get a popup dialog prompting me for a name. Nothing comes up. Any ideas?

What EDA do professionals use usually?

In my internship, I get to use Cadence (Allegro/OrCad) for PCB designing. I was seriously shocked how complicated it is (very specific on each components). At the same time, it feels like a very outdated software as well (even though the one I was…
