Thanks a lot, that's a cool data structure and I was thinking about something similar. (Actually, I was thinking about the "chart" in "chart parser" and was about to look up how these are usually implemented.)
I'm reluctant to do it on the side, though, because experience has told me that these kind of approaches can be error-prone. But I'll give it a try. If there will ever be a future change to text%, please consider this a feature request. The feature is very useful in list-box%.
