Container, the bond is removed but
its contents (orbitals, texts) is saved, linked to the first atom parent. 
When the 
Scope is 
Contents, the bond is preserved 
but all its contents (orbitals, texts) is removed. 
When the

these objects are removed from the bond.

Clicking the mouse over a bond in the current layer, its identification
