The Theme Controller plugin provides flexible theme management for Obsidian, allowing users to dynamically switch between light and dark modes, as well as apply custom themes based on the active note’s path or specific tags. It offers a color switcher that allows toggling between themes easily, and the ability to set default themes when no specific settings are applied. The plugin enhances customization by enabling users to create a personalized Obsidian environment tailored to individual workflows or content types, with themes that automatically adjust based on context.
