A little bug I noticed that will be incredibly fiddly one to fix in my experience but worth noting is when the toolbar is 'minimised' the space that it previously occupied on the screen still cannot be clicked 'through'
I assume it is something like CSS controlled? The object (DIV maybe) is still remaining at a higher z-index than any links that are behind it.
This means that when you are trying to click on a link at the bottom right of the screen with the toolbar minimised you cannot click it...
