Comment 3 for bug 983518

This is a decent mockup. I would suggest that, even though it breaks consistency across apps, the category filter for the Applications lens needs to be on the left side, so as to more efficiently be navigated when starting from the dash icon in the launcher.

Of course the current model of getting to the Applications lens is also not ideal. Somehow may be good to have lens icons on the left? Then click dash icon in launcher, move slightly right, click Application lens icon, move slightly right to choose catgory (dynamic hover would be good here as an option), move slightly right to select application. In this way, the mouse travel is very efficient.

One additional suggestion is to have the "Application description" show once an Application is "hovered over".

These ideas are used by standard Application menu launchers such as Cardapio, AxeMenu, or MintMenu.
