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.

You can's see byes clearly. Once I also embed a byes with my website https://fastlabourhire.com.au/ so that visitors can also play this game and all of them are saying that they are unable to see byes clearly.

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.
