Storyline 360: Quick Access Object Transparency Controls

Primarily for images and other imported graphics. 

On the Picture tab, where there are options to alter the color, brightness, or contrast, there could easily be a control for adjusting the transparency of the object so we don't have to constantly right click and select "Format Shape" just to make an image more see-thru. 

This could then be extended to shapes, icons, markers, etc. so it's easier to adjust transparency without having to format the shape or adjust the fill color's transparency manually.
