Thank you so much for mentioning this JIPG. I was all set to give patching a try when I carefully re-read the entire thread and saw your post properly. Overdrive support is more important to me than font weight controls, it was a delightful bonus when setting up my new Clara yesterday. I was delighted when I saw that I can finally access my library's ebook collection on an e-ink device (no Kindle support from my local libraries) so I guess I won't be installing this patch if it removes Overdrive functionality.
