Show byes more clearly
When the system pairs an odd number of players in a swiss tournament, it of course gives a "bye" to one of them. However, you need to know the whole list of players, and see which one of them isn't in the brackets to see who is playing the Bye. Just a little text to the side of that round's bracket saying "Player 4 has a bye this round" or something similar, would make it much more intuitive.
My players get super confused when the bracket doesn't include them when they have a bye. It would my tournaments run smoother if you clearly indicated in the bracket who has a bye.
