The Divide & Conquer plugin streamlines the debugging process in Obsidian by enabling bulk management of plugins and CSS snippets. It facilitates efficient problem-solving using the 'bisecting' method, where half of the plugins are disabled at a time to quickly identify potential culprits behind performance issues or bugs. The plugin offers commands to reset, restore, bisect, un-bisect, and re-bisect active plugins or snippets, allowing users to methodically narrow down problems. Additionally, regex-enabled settings help exclude specific plugins or snippets based on keywords, authors, or descriptions, ensuring a more tailored debugging experience.
