Ren'Py does have functionality for that, but it involves code & UI changes that I don't have experience with, and I also don't have a way to test anything outside of an Android emulator, which may not be sufficient to ensure everything's working. So it's on hold for now.

It's not too difficult to pick up. I only knew old school HTML programming before working with it. It's actually not too dissimilar to that. Anything I don't know how to do I can usually search for and find the answer, and there are a number of YouTube guides for it. But for a very basic VN, the tutorial does cover most of it.
I'm not sure what code editing program you tried, but I use Visual Studio Code (VSCode) which has a Ren'Py extension to make the code different colors depending on what it is, which helps parse what I'm looking at.
For YouTube, I think Zeil Learnings is easy to follow: https://www.youtube.com/c/zeillearnings
She also has an itch.io page to download templates: https://zeillearnings.itch.io/
This guy also has good videos. The very early ones cover the basics: https://www.youtube.com/@vimi
