Example for c)

I just noticed that on session restore, spectacle takes a picture of the boot screen. Somehow this is kind of useless. I am not sure, what my expected behaviour would be, but some options come to mind.
a) spectacle to be excluded from session restore
b) restoring the last screenshot, but I assume this might not be possible and may not even be useful.
c) It be "abused" to "restore" a picture which give a short introduction into the functionality / power of spectacle. Some Big Blue Button installation have some kind of standard presentation template which gives a short overview on how to use it. I will upload an example.
