I love @pinafore. I manage several accounts in it, both on desktop and as homescreen PWA on mobile.
I like how it allows each account to have its own color theme, helping to visually and mentally separate each mode and space.
It also does well at remembering offsets across many sub navigating so you can always find your way back :)
