For those useing powerlaunch,install the rotate applet and use that to rotate to portrait.
I will make changes to enable the long-home-keypress again.
I will notify you when it's done. Most likely monday.

Double click rotation and longpress is troublesome, because you will still get the powermenu. This can be prevented with short press.
That's why I chose short press for rotation.

Bear in mind this is a work in progress, so there will be changes and updates.

to rotate the screen from command line run: xrandr -o left
then play with the slide.
