Right now not good but I have a plan for the web version. I'm going to overlay text fields, buttons and other things on top of the cells where they're being rendered. This is doable because nimwave has all the semantic information.

For terminals there is no way to do this. I think we need a new standard to represent terminal interfaces that preserves this info. I have some ideas on how to do this in a backwards compatible way but I'm on my phone at a BBQ right now so I can elaborate later :P
