Speed should never go before usability.
I guess you prefer general settings over function parameters in order to keep it simple for beginners - didn’t we discuss this before, in a different topic? (Please keep reading, I have a solution in mind).
I tend to disagree with you on this. IDENTICAL TO is very much an interpretation advanced users may want to apply, and only in some special cases; a general setting is like a nuclear bomb where tweezers are needed.
Solution proposal
If you must use a general setting, ask Jens if he could create a setting to control whether optional function parameters be visible (and changeable, of course) - so beginners will not be confronted with those, and everyone will be happy (ever after 
).
