Hi Max, I don't doubt that they will be useful - but things that involve quite a bit of work tend to be inherently difficult for me to schedule since I have extremely limited development time to spend... That makes it difficult for me to try and make any promises about exactly when any particular feature will actually get finished.

Things that are interconnected involving changes to more than one existing engine piece (like both the display engine and the hidden line removal one as this feature would require) can have a pretty high difficulty level, so that's just something I want to be clear about.

But it's great to hear feature requests here, and the more different people that tend to ask for the same type of features definitely has an impact on the priority of what I try to focus on.
