A More Usable Ruler

I don’t know how alive this project is, but I wish the ruler had as many features as the one on roll. I.e. multiple waypoints and the ability to keep it visible while you move tokens around.
The current ruler is pretty bad at moving tokens since holding a token while measuring often puts the mouse cursor over the distance. It’s somewhat tolerable with a grid since the distance display isn’t always below the cursor but is really annoying with the grid turned off.
