A custom addon has to implement save/restore, if not we have "<xxx> does not implement abstract member 'NinjaTrader.Gui.Tools.NTTabPage.Restore".
But if the save/restore classes are like:
public override void Restore(XElement element) {...
the error is then:
"Cannot change access modifier when overriding 'protected' inherited member NinjaTrader.Gui.Tools.NTTabPage.Restore(System.... )"
So the example in the Help documentation is not accurate (yet), or it should work and I'm missing something?
