UI support for "transform" option

• e.g. provide a list of transformers with human-readable descriptions.
• e.g. provide auto-complete for query
  • e.g. show list of "selective features", possibly updated dynamically while completing query

Would it be sufficient to present a set of options with checkboxes and dropdowns? Otherwise, I think the widget would have to be pretty custom-tailored for this specific option?

For the second part the widget would have to be custom-tailored yes. For the first part a dropdown will do.

For scripts like the NLB version of dtbook-to-pef it makes sense to have a dropdown with a static list of options but not for the generic script I think. That would be very limiting.

Anyway, I made this issue just to capture the idea. I'm not actually planning to do something about it for now. The auto-complete idea is pretty far-fetched. The exhaustive list of transformers is more feasible.
