form items with 'grayed out' properties

I miss the ability to set a ‘grayed out’ properties for form items.

It is nice that we can change forms in runtime and can set the visibility of the item.

But if I make a form where the user can those to use graphic from the graphic layer, and the user haven’t drawn any graphics yet, then it will be wrong to remove the option, by setting the visibility to false .

Then will the user newer notice this functionality. Here will a ‘grayed out’ function be nice :-)
