The Nextcloud Link Fixer plugin resolves compatibility issues between Obsidian and Nextcloud Text by correcting the wiki-link format. Nextcloud modifies Obsidian's `[[wiki-links]]` syntax, which can cause display or functionality issues. This plugin provides an automated fix on file open (optional via settings) and includes a manual command `fix-wiki-links` to restore links efficiently. It ensures smooth integration and usability when managing Markdown files across Obsidian and Nextcloud.
