The FileName Styler plugin enhances how file names appear in the sidebar by allowing you to hide, modify, and decorate them based on patterns or folder-specific rules. It's especially useful for setups that use timestamp-based or Zettelkasten-style IDs, offering options to hide these identifiers or move them to the end of filenames. You can apply custom prefixes, suffixes, colors, and even emoji icons without altering the actual file names. The plugin supports multiple styling profiles that can be independently configured and scoped to particular folders, making it a flexible solution for organizing large vaults with visual cues.
