This question already has an answer here:
Recently I noticed the changes to the top bar. They are good but I had a suggestion, what about fixing the topbar at the top of the viewport for the user to simply access it regardless of on what position they are on the site ? I mean they don't need to scroll up every time to access the topbar.
I know this topic has been discussed earlier and the obvious answer was that use a grease-monkey script or something similar to it to make it fixed on your browser, this can be a good addition in order to make user interface better.
Thanks and hope to get some positive response :)
UPDATE: I respect your opinions and thus closing this topic.
