As I edit vertices, I usually know how far I want to move it due to consistent distances and measurements. I'd like to see a distance-moved popup bubble showing how far I've moved the vertex. You could move the vertex, release the selection and then grab it and move, knowing the straight distance right then. I work on measuring property along a rail line and know the distance from track center. Could save a ton of time when you know how far you need to move a vertex. Kinda like integrating the Measure tool into the editing features.
Hopefully others will agree with this idea.
