Sure, so:

- If you highlight more than one note it automatically scrolls, you just need to leave one note highlighted at a time and it'll stop scrolling (this isn't obvious in the UX, so I need to change how it works, maybe adding a checkbox)

- You can delete notes, just hover over them, click the green tick, then go to archives (bottom right), and delete them from there.

But thanks for the feedback, I want to release an update which helps get on top of these common questions.
