It technically does support text colouring per word, albeit it's very convoluted if writing code manually (not through adventuron.
Essentially, everything that has a different colour must be a different message. That means for example that if you have a paragraph with 10 highlighted words, then you might need to use 20 message slots. It would also use many many condacts. PAW does not have such a problem as colour information can be embedded into the message text itself.
It's something I'd like to build into the converter (as I have already built into the inpaws exporter). Don't bank on it being there before the end though. It will tear through your byte limit (which is about 29k on DAAD - not including XMESSAGES which are themselves limited to 64K).
