 ### The editor itself
 
-It's still Notepad++ at heart: a tabbed, splittable interface (Qt Advanced Docking System) with syntax highlighting for 80+ languages through vendored Scintilla and Lexilla. Macro recording and playback, session management, and an embedded Lua scripting layer are all here. If you're coming from Notepad++, it imports your config and sessions.
