# shell (hopefully dash!) places menu for openbox

# <menu id="places" label="Places" execute="/path/to/dash_places_menu.sh ~" />
# to your .config/openbox/menu.xml (you don't need a final slash after the ~)
# or, if you want the "recent files" menu incorporated at the top, use:
# <menu id="places" label="Places" execute="/path/to/dash_places_menu.sh --recent ~" />
# make sure you have recently_opened_menu.sh somewhere, and enter its path below.

# path to your "recent files" script, if you want to incorporate it:
recent_script="$HOME"/scripts/recently_opened_menu.sh
