Can you make a order system for tab list? Here my current tab list:

It seems so messy. If you can make a order system that orders players with their rank weights it will be great.

I'm still not convinced that this belongs in EssentialsX over a dedicated tab list plugin.

Then maybe you can add an option to disable showing prefixes in TAB list. Because currently it is so messy. Here a screenshot with more players:

But i still think ordering TAB list will be best.

Uncomment change-playerlist and set it to false to disable EssentialsX's playerlist interaction.

EssX still doesn't alter the tab list aside from afk, prefixes and suffixes to my knowledge. The provided screenshot doesn't appear to be related to EssentialsX.

The tab list changed when i update from Classic Essentials to EssentialsX. It gets prefixes from zPermissions.

EssX doesn't have tab list headers or footers. Nor does it currently manipulate the order in the tab list - this has been suggested before and has not yet been implemented, and I think different people will have different opinions on the sorting if it were to be added.

Yeah tab list and tab footers are from another plugin. But prefixes getting from permission plugin as i said before. Permission plugins usually have group weight option. Essentials can use it and different people can edit weight as they wish too.

This is not possible to implement currently in vanilla without using a very hacky implementation -- this involves creating "teams" with lexicographical ordering such that players in the list are in the proper positions.

Definitely something you want to use another dedicated plugin for.
