Ive added v0.3 to the first post - this has hiding/showing of non-mana bars (it will toggle display for druids when in cat/bear form)
The non-displaying of power/rage for rogues/warriors/shifted druids was a bug, and should now show properly. The various energy types are all shown in the selected colour atm - I'll get around to adding in power type coloration soon.
Ive played around with putting the mana bar over the health bar - but if you have the bar at the top or bottom, you basically lose visibility of a percentage of the actual life bar - similarly if the bar is oriented horizontally (so it depletes R2L) and you have the mana bar at either end, then you lose visibility of that.
As such, right now I'm going to leave it as it is - but at some point I will add that as a configuration option.
