xfce4-screenshooter is the standard screenshot program in XFCE on Xubuntu.
how can I configure the settings about which format it saves the screenshot in and in which folder?
I noticed, that my settings I made in
shutter also affect the settings of xfce4-screenshooter (but not all)
the man page sais, there is an -o option to open it with an external program.
how can I make this default? then I could set there an external program, that automatically compresses the screenshot to an emailable size
