[Suggestion] Consider a game mode whitelist/blacklist system.

[Lead-Lord]

Could you consider adding a system that excludes players in specific game modes from things like raids or power systems, similar to how you can blacklist or whitelist specific worlds?

With this system, it would be possible to make only players in specific game modes interact with the system, effectively preventing those who have switched to modes like spectator from interfering with power or raid systems. This could greatly enhance the usability of the plugin
