The new Attachment Browser helps Notes 4 move towards being that repository. Click on the Attachment Browser button, and a window with six tabs opens. Here, the file attachments for all of your notes are viewable; click on each tab to see its respective file type. The Browser makes it a lot easier to spot a file if you don't remember its name, which prevents you from finding it in search.
You can instantly make a checklist by selecting the items in your note and then clicking on the "Make a checklist" button. Next to that button is a new formatting button. There's also a Photos button that pops up a window so you can access pictures in the Photos app.
The Share button throughout El Capitan now lists Notes, so you can send items into the Notes app. For example, I looked up locations in Maps and sent them to Notes via the Share button. I can quickly access those locations in the Map Locations section of Notes' Attachment Browser.
Those are the major changes to Notes. We'll keep an eye on the developments and update this article accordingly up through the final release of El Capitan.
