The title says it: Would it be possible to sort invited players to a tournament alphabetically?
I know it is currently not made for KO tournaments, but this feature would make the workaround a bit easier. You can invite all players from last stage and cancel all players who lost their games. However, without any sorting of players, it is very difficult to do this. You need two windows open and find players via Ctrl+F on the web page.
This way it would also be easier for outsiders to find participating players. Since it is also done for running tournaments, this should not be too difficult.
