Interview with MT to complete a questionnaire from which she'll build a wireframe model. This was useful, and helped me to clarify a couple of ideas I haven't been sure about. I'm going to detail them here while they're fresh in my mind:

• All main windows will be dockable.
• The three main windows will be:
  • The Images window, looking much like our previous mockup.
  • The Links window, which will provide an accessible list of all the links made so far, organized by category.
  • The document browser, which will provide access by filterable xml:id to the ids already in the document, and also by means of a tree model of the document body.
• Other windows will be modal dialogs:
  • The category manager (or should this tie into the links manager?).
  • The XML editor (pops up from the document browser when you elect to edit an element).
  • The Preferences window.
  • The Output options window (could this simply be integrated into Preferences?).
• Still haven't decided how to handle translations -- presumably the easiest mechanism would be QT's built-in translation tools, but this might require separate compilation for each language -- check this out.
• One issue which came up was accessibility: is it going to be possible to allow users to define zones using only the keyboard? It's conceivable, but it might be really difficult to design and code.
