(If this is already a thing, I just need to know where to turn it on) 

Right above this text box is a row of icons. If I don't know what any one of them mean, I hover over it and a flyout tells me. 

I would love to have this ability when I'm in the thick of building a model in Microvellum. As a new user what I find to be sucking most of my time is: seeing an object that is slightly off and then zooming in to fix it only to be completely lost in lines. Say I'm trying to adjust a filler width and zoom way in to adjust it accurately. I can't even tell which line is supposed to move to what. I I could just hover over each line and have it tell me "Appliance Panel" or "Product 1.01" or even "Undefined CAD line" or "Undefined Extrusion" - this would be immensely helpful.
