> got a little confused about the stages. I think I may have set up two by mistake, at least, the "previous" button was visible when I was editing the stage

Hmm I am planning to add "templates" for stages that you select and it will create stages according to a standard template. For example, first a group stage, followed by a knock-off stage. That should make it even simpler to set up stages. I'll look into the "previous button" problem you describe, maybe something goes wrong there.

> each player is just an individual, and there are no teams involved

Yes I have heard multiple people about this confusion. The idea is that if you have only players (no teams), you just create teams with no players in them. I'd prefer not to implement the idea of "players as teams" because it will make things very complicated. I could maybe adjust the frontend though to just show teams as players in that case.
