Suggestion for Enhancement: Help List, Syntax Checker, prevent Auto Close, open in new Window

[BananenRitter]

1. A Questionmark Icon that expands & displays a List of all Expressions & Whitespace Characters with Example Syntax when you click on it
2. Syntax Checker that informs you if your Syntax is missing something/ wrong
3. A Setting that prevents the Regex Window from Auto Closing after youve replaced something
4. A Setting that Opens the Regex Window in a new Obsidian Window that you can drag around to see your Note better while working with Regex.
