Callouts are a needed markup tool. The best and most common method for making plan notes is a leadered callout. It's unfathomable that this program does not have this basic tool. The current process for faking a callout is to draw a text box and then an arrow. This is double the work for creating this single item and the two shapes do not move together, so adjusting the location of the callout also takes twice as long. Additionally, the program does not allow you to draw one shape on top of another shape, so making an actual connected leader and text box is not really possible.
