Was expecting this to be fixed in mapper version coming with MM4 but its not.
When one is editing a grid and one pushes the plus button, the number of lines in the grid double. Its not possible to set the exact number of cels one needs. Its only possible to set the number of cels to 1, 2, 4, 8, 16 cels etc. I fail to see why we don't have the possibility to be able to set a grid of 3, 5, 6, 7, 8, 9, cels etc etc etc...
Setting up one surface and dividing it into cels is much better for performance than working with a large number of individual surfaces, one of you guys colleagues suggested
So please please enable your users to work this way conveniently.
