Hi! Your question is timed well, because v1.10 will actually have a mode for this out-of-the-box that just lets you highlight characters
In the meantime, you could also achieve something similar by making each character an entry in the "tokens" – they're called "tokens", but in reality, they're mostly just a highlightable unit. And then you probably also want to adjust the margin of the .prodigy-content span (the chracters) so they're not as spaced.
Hi Ines. Thanks for the response and I am happy my request has been in the works already. I tried separating by character but didn't know about the span control. I will try that out while you finalise the 1.10 release.
