Just finished the survey - which was too short to give any relevant feedback and missed the most important part: a field to write actual feedback, putting the given data in context...
What i wanted to say there:
I can't either correct mistyped results nor drop players and do repairings if needed because of either of those cases.
The final standings should stay available for at least a day after the event finishes - if the host clicks one too many buttons they are gone. It happened more than once.
Doing seatings manually would be a welcome additional option. Several players might have impairments (wheelchair, obesity, crutches,...) that might result in reduced seating options or some groups might just want to start drafting as they are already seated ( and not play their seat neighbor in the first round if the app thinks they sat opposite)
