Add the ability to print a map to the correct scale
When "print map" is selected with the topo 50 selected, and the print option is selected as A4 portrait, for example, then the red print area should default to 10.5 x 14.85 grid squares (less about a 6 mm print margin all around). It can then be moved around by the central handle to get the best coverage of the area of interest. It is much more legible to print the maps at the scale they were intended to be printed.
Much like the "add grid numbers at sides of printed map" request... it may be put on a back-burner as it's likely to require a GIS server which will cause a lot of extra expense.
