Texstar patched the filemanager so it works without being shown in the menu.
efm isn't very user friendly but we wanted it to be loaded to have the files plugin for 'Run everything' working
and to have icons and files on the desktop.
The places gadget allows us to use a filemanager of choice.
PS if you want to check out efm you can open a folder in efm from the run everything gadget (Alt + Esc)
