So far the areas of the admin CP that I have borwsed have been really cool.  All of them do get annoying though if you are viewing them on a screen that has low-medium resolution.

If the content on the right hand side of the screen is to wide to fit alongside the left hand menu the sutff on the right gets shoved under the left hand menu.  Then the left hand menu overlaps and makes a lot of the right hand stuff undreadable.  THis causes a few problems when trying to read or do anything in the Admin Control Panel. I am running at 1024x768 and this happens all the time.

Also, when you are viewing the database structure.  It does a weird format thing where the tables don't stay right justified when they go past the left hnad menu's height.  Then it formats on the otherside below the left hand menu.
