Khanmigo and Assign toolbar

Hi! This is for those who use both Teacher Tools and study on Khan Academy as learners. Can the Khanmigo toolbar be collapsible? Sometimes -- in programming or reading articles especialy - I'd love to study fullscreen without any of those features.

But I understand and appreciate that the toolbar is precisely for keeping assign functions handy - but I'd love to see an option to temporarily hide and re-open it (open by default) to facilitate focused study.

The context bar on the left actually can be collapsed and re-opened -- the one showing Assignments and the rest of the course lessons and units.
