Hi Michael,

I can relate to lyes with center picking issues, especially when you have several arc enteties around each other not sharing the same center point it's a hit and miss situation.
It'll be nice to have something to zero in on the right acr center, maybe a mouse click key combination to pick the arc it self to snap to the center.
In regards to the object organisation stuff if you apply a style colour to an object/arc will the X marker inherit the same colour, this could help in identifing which center belongs to which arc.


Cheers
