I actually noticed one more thing about links with LRF, though I'm not sure is that specific to kovid's viewer, or is the same kind of behavior present on the Reader (it still hasn't arrived).
It's like this: I have an e-book that I'm editing in BD and I put in links to footnotes that are at the end of the book. The links are in the form of [#], where # is the number of the footnote. I make both the number and the brackets around it a link, and it works great. But sometimes, when the [#] ends up at the very beginning of a line in the viewer, the link is broken. I'm guessing this is caused by the [#] actually ending up at the end of the previous line and wrapping to the beginning of the next one.
Very irritating since I have to check each and every link in the viewer to see if it's placed correctly, and if it's not, I have to move the [#] around.
