* TapAndHold and release gesture for access to the context menu (main window, panel folder, places and information)
* TapAndHold and moving gesture for drag and drop action (main windows, panel folder and places)
* pinch gesture for zoom in main window
* kinetic scrolling (QScroller) for main window, panel folder, panel places, panel information, setting preview and service
* two fingers swipe gesture to left, right and up as shortcut to navigate back, forward and up
* two finger tap gesture to toggle item selection, similar to Ctrl and left mouse click
