I installed in manually last night and it seems to work just fine. For me it's a bit of a step back as I now have to go through one more click to get back to the reading progress indicator that I want (cycling through none) when it accidentally gets changed. Personally I'd love to have it only have two options -- time left in book, time left in chapter, possibly even on the same line, something like:
6 min/3.5 hours
