# Also, shows after the all the .desktop files on /usr/share/applications/, shows .dekstop files in the /antix subfolder
# I concatenate both .dekstop files and present them in alfabetical order, I choose to not mix both "common" and antix specific applications
# this version of the script tries to add a *.png icon. If it fails, no problem, the menu entry works, but without any icon!

#Application to pin and unpin applications to the top of Fluxbox menu
# requeriments: yad and the executable script "~/desktop-run.sh"
# that script's content is as follows (remove the # at the start of the line):
#`grep '^Exec' $1 | tail -1 | sed 's/^Exec=//' | sed 's/%.//' | sed 's/^"//g' | sed 's/" *$//g'` &

# By PPC - 25/01/2020 - GPL licence- do what you want with this script, please keep this comments about the author and date
# TO DO: a option reorder the "pinned" applications
# -- idea1- present the list of pinned applications, like in the "unpin" funtion. When user clicks on, use sed or whatever, to get the selections line number, a new yad window pops up, presenting the line number, allowing to user to increase or decrease the number. Delete current entry, create one at the chosen line number - This will take more work than the pin and unpined functions combined!
#idea2- simply create a button that executes flux menu editor, the user can then move the pinned applications using drag and drop!
