This has been mentioned before, but there needs to be a way to make it so nobody (or only my friends) can sit down at a table with me -- the allow spectators option only covers spectators and not players at the table.
I want to be able to make a table and wait for my friends, or make a table with a specific kingdom and play it with a bot. Currently the only way for me to do that is to make a table, somehow have a bot sit down at it before a stranger sits down and starts complaining that I haven't started the game yet, and also disable spectators. More than half of the time, I can't move my mouse from "kick" to "add bot" quickly enough, and someone just sits down again.
The simplest and most intuitive fix is to have the "allow spectators" option cover people playing at the table as well as spectators. It's what I expected the option to do anyways, but some may prefer changing the label on that option to make it more clear.
