Thanks for 1 and 3.
For the font size, the message text goes smaller than the list text. Could the list text not go as small? I’ve not got Super Sight but in my 5K 27” iMac the list font is larger than in any other app I use even on the smallest setting.
I don’t see me needing any of the icons on the left of the window - surely being able to hide it, like you can other panes, is doable?
