When one right-clic on a file, the contextual menu is to long. It might be good to split it by categories of actions.
I believe associating a kind of action (show, edit, manage) to a direction (left, right, down) would make searching thrue the contextual menu easier.

-On the left of the mouse could be applications usefull to look at the selected file (for example gThumb for a photo, totem for a video, evince for a pdf, run for an executable file, epiphany,...)
-On the right of the mouse applications usefull to edit (GIMP, abiword, Pitivi,  gedit... )
-And below the mousse, actions related to file management (copy, paste, move to trash, create an archive... )
