If you specify a player skill greater than 10 in Tio, it will seed based on those values. However, if you go to the Players tab and select a player who's skill is set to a number greater than 10, Tio will crash on you.
So I can offer much better seeding (basically I can assign N players skill from 1 to N, in order of their rating) at the cost of you not being able to select them under Players*. That means that you can't change their name, nickname, skill, or location anymore in the seeded version.
How do people feel about this tradeoff?
Should I just make it a separate option? What do people think about this?
*The Events -> Entrants tab is safe, but you can't modify any values there.
