Targets would be a symbol that appear on viable snap positions I imagine it as a bullseye that appear as soon as you start dragging a node.When you get near a target the it changes from red to green to indicate where its snapping to.
This pre-snap indicator might also be useful. The target could be highlighted when the cursor is within twice the snapping distance from the target. Whereas AutoCAD uses a mouse click to switch from pre-snap to post-snap, we could use the snapping distance for that. Much more snapping calculations will be needed though, so there will definitely be a performance penalty. It will also be more difficult to implement than a post-snap indicator, so let's first focus on implementing that one and see if that works out well.
