Without sounding too negative, I understand that this is a lot of work but I simply don't understand why Linux desktops, let it be Gnome, Unity, KDE or anything else always looks like a bunch of developers try to master usability.
right? Most DEs offer solutions to problems that simply don't exist. Take the launchbar on the left-hand side for instance. Being able to launch apps quickly is handy. But why waste valuable screen space for it? A simple launcher that can be activated with a keyboard shortcut is enough imho.
