[review]

Well, the way how you get there has been described elsewhere before. There is just one major bug which makes it unusable for me.

The screen update is really slow.

I'm not surprised as I've worked on the development of annotation for pdf and the djviewer before and stopped it because the screen update was making it impossible to write.

Now, if you think differently, go to scribble and write a few lines. Then go back to "edit picture" in FBReader. There are world between those two. In scribble you can write in FBreader you can't really write.
