+## 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 M`X`B`Y`, where `X` is the monitor number and `Y` is the block number. Se example below
+
+Customizable numberings (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`.
