Show Grid Coordinates

Any of the following would be extremely useful:

  1. Show the “Fixed Start X” and “Fixed Start Y” coordinate on the platform grid.
  2. Label and mark the coordinates on the grid that is already displayed.
  3. Allow the user to select the “Fixed Start X” and “Fixed Start Y” by clicking on a point on the grid.

Number 3 sounds like a lot of work, but surely either 1 or 2 would be easy to implement.
