Feature request: single/double elimination knockout tournaments

In addition to the Arena and Swiss tournaments it would be very nice to manage single elimination, double (...) knockout tournaments.
The problem of the draws can be solved with Antichess playoffs, where the draw is not expected as a result

I think the more important problem of the knockout format is, that most participants have a very short and unsatisfying tournament.

I agree in part, that's not the formula of our weekly swiss tournaments, we aggregate the weekly results and monthly do a tournament with knockout elimination (Best of 5) among the first 8 players of the month, so each player plays at least 3 games.
One of the goals is to stimulate participants to learn the openings that hypothetically are to be played...

those games are "added" to the weekly activity...
