Good to have confirmation from an user :)

Maybe the scale option should be reseted when the user select a brush ? But 
that could be confusing as well.

That would be great.

It clearly can be improved, but to be honest it's not a high priority, at 
least not for me.

Yes thats the plan, well my plan is to use the wheel mouse. But keyboard 
shortcuts are possible as well.

I think it should be up to Krita to know that there are brushes of same type 
but of different sizes and to take care to select the good one.

I don't see that as exclusive of the resize.

Well it's not that hard, I mean we are allready rescalling brushes depending 
on the pressure. I guess that the difficulty for the Gimp was to integrate 
the feature.
