Remember the last monitor the Platform was open?

I use 2 monitors and PortableApps keeps opening on the main monitor which I suppose is an ideal situation for most cases. For me though, I want it to open on my 2nd monitor. Moving it and exiting does not seem to save this preference.
If the problem is that "if you bring the USB to a computer with only one monitor, you won't see the menu anymore", then I say just check if there are fewer monitors than before and if so, THEN move it to the main screen. That way accounts for cases like that.
