I like the icon, but don't use it
I usually click the forums tab when I want to get to a specific forum.
I'm usually looking for Specific Posts though - not Forums.
If this popup had the "Last 10 threads you were in" ... I'd use it alot.
When finding people information or updating one thread from another ... I find myself opening up multiple browser windows ... especially because most of my PCs have two monitors
I like arrows when a popup or expand is below it.
Like next to your username. The popup is right below.
The quick nav takes you to the center of the page.
previously one could alter the colour palette without needing to update graphics.
now that this graphic is blue, that has changed.
i suggest the icon revert to grey.
