Please see how to use this plug-in in the following video.
I got permission from my client if I could do something similar like this Plug-in to promote my fiverr GIG for writing GIMP Plug-ins.

Hello there, bro!
[breaker]
Hi bro, can you write me
a GIMP Plugin?
[breaker]
Sure I can
[breaker]
Sweet, bro... 
Thanks!

Better version that creates layer_group for each text so that you can easily move layer-group

I did a lot of cartoons and used the Ellipse select or rectangle select (often with rounded edges) from toolbox for text bubbles.
Then I used a big white brush over them (it always stays in the select because its not locked-down), made a text and positioned it and finally used a thin pencil (make straight lines with shift key) to make the speech arrow. I rarely used 'thought bubbles'.

Point is this takes me all of 4 minutes and it is customized to the image being presented.

You could say that replacing basic Gimp operations reduces a persons ability to actually use Gimp. Instead they are very good at finding plug-ins

This is the only cartoon I did that doesn't break the GC code

For me it's when a person hammers 1000 nails, they get an automatic hammer heheh

Because it puts the texts into layer groups that's named like the text so users can choose to move active layer and move layer groups one at time which will move the text and background as the layer-group is moved.
