The expand/collapse feature did not properly account for the "orientation" setting. Expand/collapse should now work correctly for all bar orientations (up, down, left, right).
Other Changes:
Lua API bug workaround: When you change your screen mode "Full Screen (Windowed)" mode, the plugin cannot correctly detect the size of the screen. As a workaround, you should first go into "Full Screen" mode before entering "Full Screen (Windowed)" mode. A help dialog describing this workaround will now appear when screen resizing is detected.
