Hey!
This is a feature I've been meaning to add for some time, but haven't added it yet as it's not really needed for STM's main usage.
If you're using STM for dialogue text, this wouldn't be needed as having differently-sized text appear between boxes would look bad.
And if you're using STM for a static text element, you'd be able to tweak the size yourself, to a better degree of accuracy. (Since text quality/point size and size are independent of each other, this is easy)
The only time it'd be useful is for static text elements that change what they say between different languages or something like that? But even then, very long words/phrases could look weird. So I think I might be add it as an additional component that sets the size element automatically if it's needed?
size = maxX / AutoWrap or something might do it, this is just a note for myself when I come back to it later
