I am all for changes to improe things and the overall look of the sight is much better, some comments if I may.
We seem to have lost screen real estate, instead of the usable screen extending to the edges of the monitor, we now have a 80% window the forum displays in with 2 large blue borders either side. I know why this is generally done, but we now have 3 nested windows, the blue back one, the white inner, then the forum area, this nesting uses a lot of space up.
Then once we open up a post we, further loose real estate with the menu system on the right, whilst we can collapse it verticality, it steals one quarter/third of the pane already narrowed from the above.
The net result is the post we read is now in a window which uses less than half of the available monitor, can we get our screens back please
