Allow users to overlay multiple layers in 1 panel

I want to see Dee and Dey together in a single panel, like this.

The builder interface at https://gramener.com/comicgen/ should support multiple layers

Characters:

• Change existing characters
• Move characters only as a whole, by default
• Preserve aspect ratio when resizing
• Split characters into their parts
• Add new characters -- and multiple instances of the same character in a panel
• Delete characters from a UI, not just keyboard
• Add mirror as an option
• Undo feature

Speech bubbles:

• Speech bubble text should be in the center
• Allow selecting text inside the speech bubble and move it
• Increase / decrease font size
• Choose font for speech bubble
• Allow bold letters
• Allow centering of text
• Allow Ctrl-Right and Ctrl-Shift-Right to select next word
• When typing, pressing Del should delete the letter to the right, not the text object itself
