When working in a sketch with multiple lines constrained at the same point it can be difficult or impossible to delete the constraint you want to. In the example below I'd like to delete the constraint for the green line and there is a 25% chance I'll delete the correct one.
My idea is to have the ability to show all constraints for a single line by selecting a line, right clicking, and choosing Show All Constraints for Selected.

The command Delete Coincident Constraint when you right click on a line sounds good, but it appears to delete the newest constraint and is not affected by which line you click on. If this command could be changed to delete the Coincident constraint affecting the line clicked on that would also be an improvement.
