The background on the Bookmark dialog box, when adding a bookmark, is dark with dark text; it's almost illegible.

The functionality of CTRL+Tab to switch between tabs is great, and the new scrolling tiles a good addition; however, the tile/tab to which one is switching is not the Center tab in the scrolling tiles but, rather, the leftmost tile. The tile to which one is switching should be the center tile, not one to the side.
