If the "rotation animation" you speak of is the animation of the player's menu items, it has sped up for 2.0b7, but it's still animated.

I don't like the adaptive menus idea because you never know if a menu item is going to be in a certain spot or not. This is a car product and selecting menu items shouldn't require looking at the display, and taking your eyes off the road. Under your scheme, if you've got two items that are "tied" in terms of the number of times you've viewed them, and you select one of them, it's going to move to somewhere else in the menu. I'd be much more receptive to user-definable order (in config.ini maybe) so each user could set a permanent location for the menu items. But having them automatically positioned by the player software is a bad idea from a usability standpoint.

And finally, in 2.0b7, it remembers where you are in the Playlists sub-menu as long as you hold down the "down" front panel button when you enter it. It's a little less valuable to do so on the other menus since they have far fewer options.

BTW, the Wish List forum is a much better place for this, and is more likely to be read by the developers..
