See my longer answer to you here.

I’m not sure why you started a new Topic when you were already participating in a Topic about exactly the same thing, and when there was a Topic created 5 days ago that was essentially the same thing. (Also, naming a Topic “feature request” is not helpful to people looking through the titles of the recent posts, because it tells them nothing about the contents of said feature request. Titles should be meaningful if you want meaningful discussion.)

Also, since I’m not sure you’ve seen it, our new feature FAQ explains that, while we can talk about ideas all we want in this Community of Notepad++ users, it isn’t an official Feature Request until you follow the instructions in that FAQ to post the Feature Request to the official Issues tracker for the project.

Formatting aka beautifying is probably best handled by an external utility (that does that function) which can be bound to a Run menu item in Notepad++, or possibly (via scripting) something that happens automatically upon each save.
