It's unclear to me what you want done in this case. Does drawing a feature
cause it to copy the feature to all three layers? Does the user somehow
indicate what layer they prefer? Something else?

the editingtoolbar is a very small set of code -- just a simple subclass
of the Panel class. So what you'er really talking about is the DrawFeature
control... but even with that being the case, I don't understand the exact
intention you have for having the control (or toolbar) set up on multiple
layers, so you'll need to describe your problem further.
