Could you add two improvements:
1) add a decider and arithmetic combinators with 0 (zero) in a second slot, as for standard combinators

2) add an ability to copy/paste rows settings between same types in dialog. Add the ability with shift+left mouse / shift+right mouse button on the row background somewhere. OR add two buttons: get/set properties for the row. Also, this should work between different improved combinators.
Example scenario: we add a decider combinator row with A > 123 => B, and we need to copy it multiple time, because I need to change only A (in) or B (out) signal
