Created attachment 632330 [details] compose pane and 3pane menu bar and toolbar seem like one big mass. in my case, a mass of blue (see screen shot), which makes it hard to find the menu bar. need to visually distinguish / separate menu bar and toolbar - with shades of color, or divider, or both.
plus, it looks bland. BTW, this is default theme
I agree and I think just a 1px line would do the trick here.
