Density-Constant World Expansion

Density-Constant World Expansion (or DCWE for short) is a simple plugin that configures the world border of your world(s) to expand when a new person joins your server, so there's always fresh land to loot and explore, while also keeping people close enough to interact!

By default, this is configured to a root function, meaning that the border expands by the same AREA per person, and not the same DISTANCE, which avoids the issue of future expansions adding a lot more land than initial ones.
Luckily, if you choose to change this, The function field is entirely customizable! Any math equation can be inputted in the world_border.yml, which can take the total number of players as a value.

Some other features include:

• Per-world expansion!: Want your Nether and/or End to expand at a different rate? Have a custom dimension that you want a border on? DCWE can handle that! Have a different function for each world!
• Clamps!: Want your world(s) to stop expanding at one point, or have a minimum size? No need to time it just right! Use the clamp function to set a minimum and/or maximum value!
• Interval Updating!: Want your world to update its borders at a set time period (eg: every sunday) instead of when a new person joins? You can do that! Simply turn on the Interval Updating settings in the config.yml!

(NOTE: While this plugin can be used plug-n-play, I HIGHLY RECOMMEND checking out the configs and tweaking it to your fit, especially if you have an already existing world.)
