Thought bubbles gone in SL360?

FredGood​: I've never been a fan of Storyline's speech and thought bubbles.

As an alternative, consider using a standard text box. Fill it with a picture of the bubble you want to use. In the Format Shape > Text Box window, adjust the Margins as needed to place the text in a good position.

Another option: Design the thought bubble in Storyline using multiple shapes. In the FORMAT ribbon, use the Merge Shapes > Union option to combine them into one shape. As with any shape, you can then double-click to start entering text directly into the shape. Again, adjust the Margins as needed.

FYI: DavidAnderson​ did a webinar about this:
