Adding a feature in the lunar chat mod options to have a second chat box, positioned where-ever the player would like that would display certain messages in it depending on the filter.
This was a feature in labymod back in 2016, not sure if it still is, but it was a pretty good QOL feature as you could have private messages on servers or party chats separate from the main chat which could be clogged with the global chat, server messages, and other misc. messages.
The functionality of this feature on labymod would be something to the effect of this
There was a menu where you can add filtered words, such as on hypixel, all party chat messages are preceded by the word "party >," there can be an a filter where messages starting with the specific characters of "party >" are then filtered to the second chat for display.
It would also be a good QOL feature to add certain filter criteria, where if the first X characters of a message do not match a filtered word with that criteria active, then it will not display it. An example could be:
Filtered Word(s) sequence: Party > Case Sensitive: True
Filter Criteria: Must be the in the first 7 characters of the message (including spaces)
This can avoid situations where an undesired message that fits the word filter but not the criteria will not be filtered to the second chat, such as,
Party > Player123: Lets play skywars! will be filtered to the second chat as per the example criteria
Player456: Playing in random party > over solo will not be be filtered to the second chat as it does not match all the example filter criteria
This can be useful not only to players, but potentially staff members of servers who use lunar client, as they can filter in game staff chat, reports and other messages into the second chat for easier visibility oh important messages.
With these filter criteria, it can save some effort for having to code special conditions for different servers, such as hypixel and wynncraft.
