A simple addon that saves the state (minimized/maximized) and position of the engineer's pet action bar. Currently, the game sets the bar to its default position for every new game session or when reloadui is called. This addon prevents that so the bar is where you want it all the time. There is also an option to hide the bar so it never shows.
This does not replace the ClassResources addon, but uses a hook to access it.
If you want something similar for the group window: BetterGroupWindow
Use /bbb to access the settings where you can set the bar to never show.
