measurements with snap

[jon-daemon]

Is it possible to take measurements with the ability to snap on edges and/or corners while placing markers?
It's a feature I'd love to see since this was my primary use of netfabb basic and I cannot find an alternative (on Mac OS).

+1 : "magnetic" points
Congratulations for this elegant "meshy" that I use for measurement of openscad generated objects.
Without magnetic points you are obliged to zoom to be sure you are "not too" far of the edge...
