When you change the orientation of RocketDock from Top or Bottom edge of screen to Left or Right edge, what was the leftmost icon becomes the topmost. Meaning the position that was easiest to click when the orientation was horizontal, is the furthest away when the orientation is vertical.
Manually reversing all the icons would be a big pain, esp. if you decided to change the orientation back to the original. It would be nice if there was some automatic way to reverse the order of the RocketDock icons with a click.
Seems like it should be a feature in RocketDock but since it's already stable on W7 I don't think they'll be updating it soon.
