@ignaloidas There are two panes, for practical reasons. We thought about adding more but they impede the view and we don't want to.
Which by the way is something these busybodies seem to fail to realize: These old windows weren't made in so many small panes because they look nicer or were better. They're made that way because large glass panes weren't easy to come by or stable enough. So a huge extra amount of woodworking had to be done to make all this extra framing to work around these limitations.
Practical reasons that no longer apply. We can have nicer, more insulated windows now, hooray! The rest is just fear of change and failing to mind ones own business.
What if someone chose to paint their house in rainbow colours? Raging townsfolk with pitchforks? Molotov cocktails? Lynching?
