I created this to quickly open wanted app. I hope it will be useful for somebody. You can quickly find application via keyboard or recently used menu.

After hiding you can show it via qtquickermenu icon or
in QtEdger:
-set right3 to dbus-signal,
-decrease velocity (if you want),
-create empty qtquickermenu profile

To replace hildon launcher add: replaceHildonMenu=true in ~/.config/qtquickermenu/settings.ini. It require modified hildon-desktop: hildon-desktop_2.2.155-2+thumb0_armel.deb (it doesn't work in portrait mode).

Latest 0.0.7 version thumb/non-thumb
