There's a lot of things that need to be done manually currently during a playoffs that can happen automagically:
Automatic entry of player in future match when player is ready (related to #7). This could be both based on league position (to populate the first match for each playoffs player, ideally first when a table position is guaranteed (#70)), or based on match result in earlier match (so the winner of Minor Semifinal goes to one of the spots in the Grand final for example). Bonus points if player is blank in different views until resolved. Extra bonus points to try out if it's between two or three players that we add a "Thord/Lukasz" for example, but it's very likely better to have only blank.
Different views should update automatically when a match is done. Schedule should update with actual result. Upcoming matches should be updated with correct players. Standings should be updated when players are eliminated.
Active match should become "next match in schedule", for views used in streaming, or for easy selection in scoring application by the actual scorer.
