Hi,
YARPP is already a great plugin, and I look forward to trying the new v2 when available.
One thing that I would like to see is sentence-aware excerpts, similar to the output of the Fancy Excerpt plugin at http://www.semiologic.com/software/wp-fixes/fancy-excerpt/
Personally, I don't like seeing half-sentences, and the Fancy Excerpt plugin does a good job of displaying only full sentences in excerpts, but of course that doesn't affect the excerpts for YARPP - if you could add a similar feature, I would certainly appreciate it :)
Regards,
Samantha
