Thank you very much for your feedback, and I'm glad you like it!
Also, I notice that you mention the Bedrock edition. It might be a good idea to make the plugin fully compatible with Geyser. I'll look into it soon, so maybe it could be part of a future update!

Thank you very much for your feedback!
As this plugin is still in its early days, your encouragement is greatly appreciated, and I am delighted that you like the plugin.

Thank you for your feedback!

However, I would like to point out that this is an exclusive add-on for EssentialsX. Therefore, supporting ServerSystem or CMI, even though I understand the idea, would go against the original concept of the plugin.

Furthermore, I would like to point out that EssentialsX has an average of over 60,000 active servers, with an average of 70,000 players connected. (According to bStats.org)
This clearly shows that EssentialsX is much more widespread than these two other plugins, which do not exceed the half of the number of servers in number of downloads (according to spigotmc.org).
If I may now give my personal opinion, I would only recommend EssentialsX as a “main” plugin. CMI is very comprehensive, I won't deny it, but perhaps a little too much so, and above all, it's not free. As for ServerSystem, it seems fine, I haven't tested it, but unfortunately, it doesn't seem to be multi-version, at least its latest version only seems to support 1.21+.

Have a nice day!
