Where is the presentation mode? I used to be able to find it in the main menu, and can't seem to anymore. It might be related to an E upgrade that (re)moved it, or the fact that I took about a month's break from E24. 
Frankly, I've seen it before too but am just not sure if it wasn't E16. 
I cannot find it on E24 either ..... which is a specific problem on E24.... i.e a lot of the offered stuff does nothing at all (is a remnant of E17) and is hard to find in the first place.
Given that a lot has to be coded in the first place and then added in such a way that total noobs understand what it does is quite a feat ..... E24 isn't easy and is actually killing itself that way. 
Not to mention the painful settings menu. I accidentally deleted half my configuration trying to back it up using the profiles settings page because i thought adding a new one would copy the existing config. So I selected it, and now a lot of my settings are gone. 
After asking Raster in IRC, I was told that it was removed because some people forgot it was on, checked blanking settings to no avail, and forgot about the presentation mode buried into the menus.
