Yeah nobody needs tools and menus anymore. We should all memorize every shortcut key VS has to offer. Then there would be no fussing about icon color nor menu casing. I guess that would give us something like this (but without the menu of course). Content is king!
I was only speaking from personal experience. I've been using Visual Studio since it was called Visual C++. Over the years, I've found that the shortcut keys are just more natural especially as most of my time I'm typing rather than mousing. (Maybe a hangover from my DOS days)
But as for icon colour, yes that was an issue. But the new release candidate seems to have sorted out the issues i had with the colouring (or lack of it)
