# Description

![highlightedEditor](https://github.com/kwaroran/RisuAI/assets/18527479/17aa1b99-39b8-48c4-98b4-0c0e20dc1a44)

I have added an editor and settings that highlight asterisks, quotes,
and backticks, similar to AutoMark, using a CodeMirror-based editor.

1. Added the CodeMirror5 package
2. Added language and settings for "useAdvancedEditor"
3. Wrote AdvancedChatEditor.svelte

Thank you for your hard work on the project.
