It would awesome to get preset positions: Top vertical third, middle vertical third, and bottom vertical third for rotated monitors.
Sounds like a good idea to me. Keep in mind though, you can already achieve this with the "Custom Move / Resize Window" action. You can set it up by percentages relative to the screen size.
I would love this as a default for vertical monitors, would be a way more useful default!
I need this too
Is this feature available, I need it too.
