FilterMessages

Allows you to define text to be filtered in the main message box window widget.

You can configure the strings to filter (separated by "|") and if the matching should be case sensitive or not.
Some options for common strings are also available so you don't have to type them out yourself.

Regex is also supported, so if you want to ignore something like
- "Something opened a door far away"
- "Something opened a chest far away"
instead of typing both, you can use
- "Something opened .* far away"

Has a context menu when middle clicking the player to also manage the settings (see note below for character limit on the filter) which can be turned off from the config file or with the mod below.

Settings can be adjusted in the config file that appears on Elin\BepInEx\config after the first launch of the game with the mod enabled or by using https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3379819704 (allows changing the settings without restarting the game).

Note: For defining strings the mod above has a 24 character limit for now, so I have added a context menu when middle clicking the player to manage the mod options and that lets you input 100 characters, if more are needed you need to edit the config file manually.
Mod Config GUI has removed the character limit on the filter so you can configure it through there instead of doing it manually.
