This mod will give Jokers random names instead of using the same name for every Joker. There are a few options for selecting the format of the name as well as using names from a custom name pool.
The mod utilizes Keepers' name system but it also works fine without Keepers, players that are using Keepers will be able to see the custom names even if they aren't using this mod.

You can also find this mod on GitHub, so if you want to help with anything, feel free to fork the project, make changes and create a pull request when you're done.
