Chat filter for CrystalChaos.net. Hide other players' messages from your chat and keep your payments visible. When you receive money, a popup appears above the hotbar showing who paid you, the amount, and the sender's skin — even if the payment also stays in chat. The filter is fully customizable from the in-game menu (key O): choose a mode (hide all, payments only, whitelist), manage your whitelist, toggle the HUD indicator and rebind your keys. Compatible with Lunar Client and vanilla Fabric. Requires Fabric API.
