v1.0.16 fixes some bugs and adds some new features:

• When setting the text of a TextDisplay, you will now have to option of copying the old text to your clipboard
• A bunch of tools can now reset the value they control via the offhand key. These tools are: yaw, pitch, translation (x,y,z), scale (x,y,z), left rotation (x,y,z) and right rotation (x,y,z)
• Admins will now be warned if they are using the messages.yml file and it is no longer up to date or missing entries
• The use of the messages.yml file is now off by default and can be enabled in the config. This is to prevent item descriptions from becoming out of date due to neglect from a server admin

If you are using the messages.yml file, you will need to set "use-messages-file" to true in the config.yml now!!!

1.20.6 has also been verified to work with DisplayEntityEditor
