Starting board numbers
Could you have a field for setting the starting board number.
With several divisions, 1 division could start on 1, the next on say 21. This would make it easier with 1 set of table numbers to keep divisions separate.
You CAN actually do this already! If you click the “Settings” button next to the division name (Division Settings) you have all sorts of options including Table Number (start number) and number of rounds planned. Changing the number won’t update any already paired rounds, so you need to do it THEN pair round 1.
