Hi,
I would like to know if we could have other speech bubbles for, for example, when a character screams or thinks.
There are all kinds: for fear, love, shyness, etc. But anger and thinking seem the most importants.

I understand that the bubble has to adjust to the content so it may not be possible ...

Hi, Check how bubble's "left" and "right" appearances are implemented; you can add other appearances like that.
