You could store the matches in a HashMap as well, using some MatchId type as the key, i.e., HashMap<MatchId, Match>. Then you can use that as the reference in players: HashMap<String, MatchID>. Only downside is that you have to generate unique MatchIds, e.g., by using some counter.

I have the F62 for about a year now. There have been no issues so far and it’s really pleasant to type on. The only thing I don’t really like are the stabilizers of the left shift and the enter key, specifically the lack of actual stabilizers. At least on my unit, these keys are not exactly smooth.
