In the name of screen space, it makes sense to only include the viewport depenant buttons in the 3D viewport. All other buttons can be located elsewhere, with the exception of tools. I can give formal definitions of these at a later time.

That being said, let us move all the buttons that do not care what viewport you are looking at to either the properties window or the information window.

This change makes sense, and I am suprised it has not been done already. There are two other buttons up there that change what "mode" blender is in, why not have a third? (the two buttons I refer to is the scene button and the render engine button.

I agree with that idea. Ok that is a 3d view 's relative selector, but it apply to all the 3d view, and we already have mesh information in the top side of the Blender's window. That makes sense.

I disagree. It does not make sense to see mode in which is active object in a Video Editing screen layout.
This piece of info is influencing only UI of a 3DView Editor in a Scripting, Game Logic or Compositing screen layout.
A problem in Blender is that UI is too much dependant of active object.
When skinning a character, armature can be in pose mode and mesh in weight paint.
Actually, we can have an object in sculpt mode and another one in texture mode and switch from one mode to the other by changing active object with a right click.
In the future of Blender, maybe that UI could display caracteristics of 2 modes at the same time for better ease of use.

I think that it would be a mistake to give too much importance to modes of active object by putting this switch in an info bar, present everywhere.

For my own sanity, we should have one "task" aka "discussion thread" per window or topic. One for the render settings, one for the toolbar/properties panels, and additional threads where needed. That way we can be sure that none of these great ideas are lost to the dark depths of the internet.
