it happens a lot where i am working in one document but i want to add some things to some other document, (which i normally do by using the ctrl+o hotkey to search for and open the document, add the note, then ctrl+o and search again to get back to the document i was in)
it would be useful if there was a hotkey that would let you switch back to the last document instead of having do all that or without having to use the sidebar.
the browser back button usually works ok if you are just writing a quick note, but if you end up zooming into a few different items then you have you have to go back through all of them to get to where you were originally
