There's still an awful lot of wasted space when viewing notes - I have lots of long notes and the layout still insists on squashing notes up in to a narrow column - as you can see from my screen snip below.
A pop-out option to get a note in a separate sizeable window would also be excellent. I often need to position a note along side another windows (such as a Remote Desktop connection for example) which is cumbersome when the note is attached to the entire 1Password window!
