Syntax highlighting and file explorer when editing file

It would be nice to have syntax highlighting for common filetypes when editing a file like .yml or .json and maybe Minecraft-specific file types like Denizenscript (.dsc) and Skript (.sk). It would also be nice to have an explorer on the left side when editing a file to show you the folder structure and file, which can also be used to jump to files etc., like the explorer in VS Code.
