Add a mod that forces these 2 settings to be set to the users preference on every text display:
Text shadow toggle (enabled/disabled)
Background opacity value (0-100%)
Text displays have more settings but text and background colors should not be changed by the client.
This is useful because some people like one of the following types of text displays:
no background text shadow disabled
no background text shadow enabled
background text shadow disabled
background text shadow enabled
If a server uses text displays then its not possible to choose how you want them to look because its forced by the server. (some servers even use text displays for nametags so lunars nametags mod doesn’t work on these servers)
Text color and background color should not be changeable in this lunar mod because thats important for the server but people should be able to choose if they want text shadow and background or not.
