participants list
This is sort of a two-part ida due to how I use Challonge, but I'll start with the main idea feel free to ignore part two... I would love to see a way to save "participants" to an account-wide participant list, maybe called "previous participants" that I can use (via checkbox or something) to add people that have been in previous tournaments to a new tournament so I don't have to re-enter names.
I use my phone to run pool tournaments so hand-entering the names on my phone before each tournament eats up a little bit of time. If I had a list to pull names from that would be great! (As most people that play have played in the tournament at one time or another -- and from week to week I'd say at least half of the players are the same).
Part two of this (and I guess somewhat less important) is that it would be great to be able to have a field to enter in a value for each participant (I'm sure others have use for this but for me this is a FargoRate ranking for each player). With an option to show this on the bracket next to their names. As it is right now I enter in the player's name followed by their FargoRate score (which I look up before the tournament starts). So without this the first part is only minimally time-saving for me as I'd still have to go in an edit the "name" which has the FargoRate score after it for each player. (Although even without a optional extra field for each participant I imagine an overall list would be of help for others).
