Customize Application Browser

Is it possible to customize Application Browser in a way that it displays only applications i want as I use both Gnome and Gnome apps and there are just too many there.

Well if someone wonders I found the solution (i made a mistake I should have written both Gnome and KDE apps) and it’s called Alacarte but there’s a BIG BUT when hiding some apps I didn’t want to see I lost possibility to adjust volume in Totem???
Which is completely weird as it’s not changing any configuration files or anything like this or is it(excepet gnome main menu conf file) ???
