Can also confirm the "scroll bug" here. When you have a page that has content that goes beyond the height of the window, the editor snaps back to the top of the page randomly. It's kind of hard to explain. The best way to reproduce it is to paste a bunch of dummy text (lorem ipsum) into a note/snippet, and then scroll to the bottom and start typing for awhile. You'll notice the app "snap" back to the top, or in other words, scroll immediately to the top of the document. This makes editing really a pain.
