One thing I really miss from Solidworks is the ability to click on a line and have the program automatically display in the side panel any constraints applied to that line as well as each of the end points. It would also show any references that line has (references to outside parts would be nice as well)

I know Inventor has a "show constraints" option. But, it is very tedious to look for the tiny tool tip that you're searching for. A lot of times the tool tips overlap, and when you're in a 3D sketch, there is almost no hope in dragging overlapping tool tips apart from each other so you can see them both.

A simple show constraints dialog box that displays a list of all the constraints applied to the selected geometry, and highlights the other object that the constraint references would be nice.
