Two suggestions that would facilitate manually adding games to a schedule:
1) Create a "metadata" screen that allows the user to specify number of game slots to add, as well as any "constant" data for the games being added. E.g. if a new field becomes available, the coordinator may be adding 20-some games all on the same field. So instead of selecting the same field/time/whatever for each game, and only adding 10 at a time, I could add many more at once, and not have to fill in the repetitive attributes for each game.
2) Allow users to select teams by name OR by team number. Our league has 48 teams, so not all of them are visible in the dropdown at once, so I need to either scroll through the list to find each team, or I need to have another tab/window open with the list of teams ordered by team # (and I would have to manually create this list, since I don't see an option to show a list of teams ordered by team #). It would be exponentially faster if I can tab through the dropdowns and just type the team # and have it come up.
