Idea: To truly allow online players and offline players to coexist!

I came up with a great idea that online and offline players can coexist without being affected accordingly. It can be used as a reference for developers.

Online players will enter the game with their normal names and UUIDs, while offline players will have a prefix (such as ".") added to them under the influence of the plugin. For example, an offline player's name "Steve" will become ".Steve" when entering the server, and their UUID will also be the corresponding name (this may require ProtocolLib), so that online and offline players with the same name will not conflict, and you can tell whether they are genuine or offline player IDs.

At the same time, if the server has been registered by an offline player before, online players with the same name can also register to the server normally. It can also effectively increase the server's reputation, because the online players here are real online players, not offline players who randomly change their names to impersonate online players.

We can also do something else, such as the permission plugin GroupManager. When first registering to the server, online players will be assigned to a new user group, which is different from the default group for offline players.
