Freely adjust the curvature of Curved Text

Currently, we have 3 options for curved text: circular, rainbow like, and then and upside down rainbow, if you will.

I think having the option to adjust the curve manually would make this feature even more convenient, useful, and dynamic.

I would greatly appreciate if you would consider adding this feature, as currently, it seems my best option is to use Illustrator on my PC. I'd also like to request bringing Illustrator to Android as well.

Thanks!
