Also, your request about fading in/out text is totally valid. I added the "All At Once" read order option for this case, but it seems a bit hacky in practice. A friend asked me recently if you can control STM's colour with unity's animator, and I'd like to make it work that way, sometime. (Right now, Rebuild() would need to be called every frame the color is set) This wouldn't work with gradients anyway though, I'd have to add additive/multiplicative gradients, another feature I was debating on for a bit. (Would require a re-write of STM's colour system)
If you haven't figured it out, you can use the Unread() function to make text use a draw animation in reverse, too! Under "functionality" in STM's inspector, you can customize which animation is used.
