When creating wiring diagrams for UI’s for example, or creating UML sequence diagrams you need to draw a lot of horizontal and vertical lines. It would be really helpful if there could be some visual indication when drawing or extending lines that the are horizontal or vertical - a bit like the indications when you have something aligned with something else.

Try holding Shift when creating a connection line, it will indicate a straight horizontal, vertical, or diagonal line. Does it help?
