I'm not sure what you mean here. You don't close notes unless you're opening them in separate windows — they just appear in the right-hand pane like any other item. See Steps to Reproduce for the kind of description we need.
In the PDF viewer, when i create a note items from the side "Notes", after i create it, i can't close it by use the " < " button in. When i restart zotero, the " < " button only work in the first time, and i open notes again, the " < " button repeat not work. Finally, i have to eastablish a new Note from the collection, where i find my item, and create a new note.
