I currently use Libretto which is a classic theme which has had no development for some years. I would like to be able to use this theme in a full block editing mode (not hybrid) in Phase One of the project. I will then migrate an existing site which uses Libretto and then in Phase Two of the project make some enhancements to the theme to be costed separately. The final result will be a theme which is unique and different to Libretto but bears a family resemblance.
