like the nest function use it daily 
one thing which i reckon would be nice would be boarder off sets,
see if i can explain this so it makes sense
sheet size 1240 x2465
my hold down clamps are 20 mm ,at present i would need to set padding at say 27mm to miss them using a 6mm tool with outside tool path ,
which makes the gaps between inner parts 54mm , which than creates a lot of waste and objects don’t fit sheet
something like margins used in word so i could set that at 27 edge of part sets there and inner padding cab be say 15 mm
