Go back to the previous version and layout of Reader!
Go back to the previous layout/version of Reader, this new version is terrible! Just making something new/different doesn't make it better and most software companies seem to be struggling to actually improve their product, so they slap some new stickers on it, move things around and try to convince us that we now have a better product to use - yeah right!
I completely agree here. The new UI is not an improvement, but makes it more complicated to use.
I agree wholeheartedly - the new UI is unusable for working with the commenting tools in a meaningful way. I need at least two additional clicks for inserting/replacing text now each time I want to replace/insert text, which is devastating from an efficiency perspective.
