There some tools the "Option window" opens without double click. Like "Align", "Freeform Blend" "Multi Surface Draft". Some Tools don't do that. i.e. "Surface Fillet" does sometimes and sometimes not. If found out the behavour is somtimes changing when I activate or deactivate construction history. But it is not allways the case.
I know it will be opened if an Entity with construction history is select. But some Option Windows are opening everytime. This si confusing.
I find it helpful if I use shortcuts that the Option box is opening as I don't have the oportunity to double click.
So one idea is to set the Option in every tool whether it should be opened or not (I would prefer that) or in General Preferences.
