Looks good (just one comment), but please add a .. note to the Operator Reference section for distance from explaining that when passed objects it just computes the distance between their positions (i.e. their centers), and that if you want to find the separation between two objects taking into account their shape and size you should use minimum distance from.

Also the minimum distance from entry needs a .. version-added directive. You could put version 3.2 for now I guess, or maybe something like "unreleased".

Looks good, thanks Eric!
