The ACE Code Editor plugin replaces the default editing experience with an advanced code editor powered by the Ace editor. It brings syntax highlighting, code folding, and live previews directly into your workflow, making it much easier to write and manage code blocks within notes. It also lets you manage and edit CSS snippets from a dedicated panel and supports quick previews of full code files. Whether you're jotting down small scripts or maintaining full snippet libraries, this plugin adds practical flexibility for anyone dealing with code inside their notes.
