Removes the dropdown arrows which were introduced in Gnome 3.10 from the App Menu, System Menu, Input Menu, Access Menu, Places Menu, Applications Menu and any other extension that wants to add dropdown arrows. --- For Gnome 3.22, please see GitHub page for an updated extension (review process is quite slow here).
Note: Binary files aren't shown on the web site. To see all files, please download the extension zipfile.
OK. Note that the 'accessibility' and 'keyboard layout' status icons are separate menus with their own arrows - you may want to consider removing those as well.
