In progress score entry/display
Allow entry and display of scores during a running match.
And
Allow API access to update scores in a running match so mobile scoring apps can integrate with Challonge and have players live score updates show in brackets.
I'm focused on pool tournaments where it helps for directors and other players to know how close a match is to completion in order to plan and notify next match opponents playing on that table.
Also when tables are far away from director and players are slow to return and report match is complete... the scoring app can instantly record match as complete. Reducing delays in starting next match.
An example app is Biliard Score Pro
