Feature request from Quinten Uijldert:
I'm using feh on a disassembled laptop which sits in a picture frame to display the family
photos, and it works fantastic. There is however something which I haven't
been able to get working, which is a playlist reload/directory rescan
function. What I mean with that is that because the laptop does not offer
any local access (keyboard/mouse are both hidden/disabled), I have installed
samba and enabled ssh access so I can remotely drop files into the picture
directory from another location and restart the laptop using ssh. As the
laptop boots up it starts the slideshow using the picture directory and will
endlessly loop through the available pictures. When I however drop some new
pictures in the directory, these are not being displayed until the next
reboot/restart of feh/laptop. So what I am wondering is if you could add
some sort of mechanism to either rescan the directory at a periodic
interval, or add some signal processing so you can send a SIGHUP to it to
restart it without actually quitting.
