Although, the OS X wrench menu is redundant, Google probably wants a
common look across different OS's. I do think the Wrench Menu needs
simplification and perhaps a UI refresh.
Many of the commands are unnecessary. For example, the "New Tab"
wrench menu button should not exist for the same reason there is no
wrench menu button for refresh. As for the UI, the items could be
represented by icons (as in the FF aurora mock), with more buttons
(like the current edit controls), or in a cleaner list with fewer
divisions and more natural folders.
