How to Hide Console Messages with Console Filter Mod
Filtering Console Spam
Console Filter Mod hides console messages that contain strings you configure or that match regular expressions you provide. It works on either the client or the server, and it is not required on both sides, so you can install it only where the noise appears.
The config offers two lists. basicFilters hides any message containing one of the listed strings. For example, adding "Can't keep up!" and "Player moved too quickly!" suppresses those common warnings. regexFilters does the same using Java-style regular expressions, which is useful when you need pattern matching rather than a fixed substring. Remember to escape backslashes, so use \s to match whitespace.
A message is hidden if it matches any entry in either list. To stop hiding something, remove its string or pattern from the config and reload. This keeps your console readable without changing how the game itself behaves.
