I recently discovered (using 2010) that you can toggle leaders on and off, as well as their styles from a right click. This is awesome and eliminates the need for some duplicate style that merely show/hide a leader from the style they were copied from. I would like to see more: If I could toggle the label background mask by the same method I could cut my line and curve styles in half!. Please add this feature!
I second that.
Also, can you set the default behaviour somewhere, but still have the toggle available? I can toggle the leader tail on or off, but I see nowhere to set a default for no tail.
Credit where credit is due! Give kudos or accept as solution whenever you can.
