"I also liked the way Plugin Notes coloured the background to make the notes stand out, although the method of selecting the colour by hex code was very poor to use."

"The old has some nice background selection,. easier to identify them in group. instance i use red bg for danger /dont deactivate series of plugins, is that possible here ?"

Would love to see color coding and make author and time a mouseover so it doesn't eat up screen space.

I would love to see this - to have the ability to colour the note background - ideally being able to select a different colour for each note icon.
A filter would be very acceptable.
