I suppose this is the wrong place to ask this since it's a question about solo playing a healer 8|

I took my resto-shaman into a 25x Naxx and my healbot doesn't have room to display 25 characters.
I ended up changing the settings to only include the groups I was supposed to support ( we did things like odd groups go left so I setup healbot to only display odd groups )

is there any setting on heal bot to use two columns, two columns of 12/13 would fit on my screen, just one column of 25 doesn't.
or is there a way to reduce the size of the bars healbot uses so that I can hopefully get all on the same screen.
