I love the ruler, it works great for combat distances and the like but I also use pages for overland maps and it would be really useful if I could adjust how much each 5ft "measures" as. For instance, I have a map up on a page right now where one five foot grid is equal to 10 miles. I can (and have been) just calculating it myself (it's not exactly hard to just say that it measures as 30ft so it's 300 miles) but it would be really neat, especially for maps where the scale isn't that easy to calculate, if I could just adjust it so that 1 inch was equal to 10 miles via the ruler (the ruler specifically, the preferably the grid would be separate).
