Rotating and deleting pages directly in EN was essential and not only to me - see multiple posts inside and outside of this feed. I cannot accept Evernote to removing this from an application - this feature was significantly driving my decision to go for premium years ago and to trust EN to host my important content. I understand that there is a strategical decision to replace an application with a browser (viewer). Whoever took this crazy decision, the benefit seems to be on a short one for Evernote, not for the customers. It will have long term consequences (as any decision). At least, through your explanation I got out that staying a customer of Evernote does not make big sense to me, thank you.
BTW: I took the possibility to send a feedback (as explained in your post) some days ago - not only about the PDF editing feature, also positioning of several meta data controls on opposite corners of the screen and overcomplicating search function seems to me as just not very smart.... but what is the benefit of sending feedback? I never got a replay and I have no idea if this influences any development decisions. It looks more like Evernote is not driven by customer needs anyway ...
