Hello,
 
I need to place markers on my stacks. Since they are large volumes, I wanted to use Terafly. However, when I try to place markers in a volume rendered by terafly a pop up windows says this has been disabled and to use the annotation toolbar of Terafly instead. The problem is that in said toolbar I can not find any options for placing makers (although there is one for changing the size of the markers).
 
Any help would be much appreciated! (I am using windows)
