David, I am asking for choice. By making all the settings -- just in time when they are needed is of course one natural option
Of course, for a very busy teacher, with a large class and a number responsibilities beside minding workshop -- I need the ability to make those choices when I set up the workshop.
Delaying the time is not natural -- but forces me and others to be tied to managing the software.
I am suggesting that in the interest of flexibility and useability -- if it can be done -- than it ought to be done.
