Differences from original:

Block system. The screen(s) are divided up into a given blocksize. E.g. in your .grid file:

[Groups]

  NumberOfGroups = 36
  Blocksize = 7

Blocks are used MXBY, where X is the monitor number and Y is the block number. Se example below

Customizable shortcuts (doesn't have to be the group number):

[25]
  ShortCutNum   = 4
  GridTop       = [Monitor2Top]
  GridBottom    = [Monitor2Bottom]
  GridLeft      = [M2B1]
  GridRight     = [M2B2]

  ShowGrid      = 0

The above has shortcut number 4 and not 25.
