Thank you for your feedback. I'll add that to a list for a potential update. In the meantime, an option to make the text more readable whilst playing through the framework is using the Accessibility options (which includes Font Override options, Text Size Scaling, and--if you are using the downloaded version of the framework in Ren'Py's Launcher, instead of the browser version--a High Contrast Text mode as well) in Ren'Py by pressing the hotkey "A" while the framework is running.
