There's a lot of Unity hate going on, and I admit, when it first launched it was an utter failure. You couldn't resize the icon bar, it was missing a lot of useful keyboard shortcuts, searching for a program didn't allow you to directly launch with the keyboard and it was otherwise just generally unusable. I decided to give it another shot recently, however, and it's come a long way, even matured into a fully usable and efficient UI. I can auto-hide the iconbar, resize it, and the search box is fantastic! If you press the "Windows" key, it opens up the search interface. You don't even have to type the name of the app you want, just start typing what you want to do! For instance, if I type in "gam" brings up Steam, Minecraft and ScummVM. If I hit enter, the first item in the search results will launch. Then I discovered the new keyboard shortcuts. Hold down the Windows key and a keyboard shortcut cheatsheet will appear, and they are incredibly useful. I am now a fan of Unity.
