The Theme by Folder plugin allows users to automatically switch themes based on the folder of the currently opened note. You can assign different visual themes to specific folders, enabling a more contextual and personalised workspace. It also supports a fallback theme when no folder match is found, ensuring a consistent appearance across the vault. The configuration is straightforward and accessible through a user-friendly settings panel. This lightweight plugin is ideal for those who manage diverse content types and want a visual cue or separation based on their vault's structure.
