What Raadec mentioned reminds me of "Structural Systems" - that's the name of the Q2 Manual page that describes doors and the like. This could be an idea for a unified article that includes all of these. The main advantage is convenience - the reader can see all relevant stuff in one place.

And the main disadvantage is that all such links in the already done walkthroughs will have to be updated :P
