It made so much sense as a way to enable really long annotations, while at the same time being a really laborious process, that it made me think about how something like this could be made easier. I thought about continuing that thread, but it's equally relevant to your posting about zooming and annotating, and it really is a feature request, so I started a new thread.

Anyway, I think it's especially important that annotation is smooth, because (1) each e-ink refresh takes time, and (2) the point of annotation is getting thoughts down quickly. Jotting directly on the displayed text has the advantage here that it's very quick, while my idea requires at the minimum highlighting some text and then blanking part of the screen as a prelude to writing, and then blanking the area again and redisplaying the text after annotating. Double buffering could help, and I think it could still be fairly fast if done well.
