When moving or placing any item on the base board display the distance from the closest baseboard edge.
Now we have to switch in and out if the ruler tool. Hard to count grid lines in 1/2" steps or less steps. Just take the ruler measurement from the left side and top and have it follow the item.

Agreed, I want to keep all track at least 4" from my benchwork edge. I'd like to know when/where I've violated that, so that I can adjust either the track or the benchwork.
