New interface is anything but urgent, however, could do with a clean up.
1-Not a big fan of Tabs, but Dockable Palettes would help, but right now, i'd just be happy to be able to resize them ALL, not just some. Especially the smaller ones.
2- No comment.
3-i like multiple screens, so, if extra views could be placed on another screen, toggling the main screen still using the Number Pad would work . . . .
4-Maybe, but there are so many "Spanners In The Works" that need sorting that this can wait . . . . . Fix the foundations first.
5-With this is one, Tabs might just work. Quick access to 3rd party Symbols then back to the current files RB Symbols Tab.
i'd still prefer that everything that we already have just worked smoothly, before dedicating the the team to inventing newer ways to eat a slice of jam on toast.
