When a button that has two settings ON and OFF and a decent visual representation what it does it is clear enough. If for instance ON means 'unit members are spread out' then OFF obviously means 'unit members are not spread out'.

And any sane well-minded player would be using keyboard shortcuts anyway combined with the mouse for overall better and balanced control.

I think it has to do more with what a person finds more enjoyable or clearer and so on, not really if it's objectively better or not.

But they -- CA and whoever exercises.... "certain control" -- should really consider more flexibility regarding setup and the likes. Then again the more options and flexibility the more likely the general difficulty of the interface or the game increases: if it's kept simple, clear, and highly effective, it's good; the more things there are to tweak or to pay attention to, and such, the higher the chance of unnecessary confusion, redundancy, or learning curve.

But for experienced/veteran/power players it could be very good.
