I liked the new/current reader on desktop, but I couldn't get it to work well on mobile, which is primarily how I read. Thanks for leaving in the option to switch back. I appreciate the work you put into it, but sorry, I gotta side with convenience.
Not hard enough, apparently, because even when it was released, I complained in the forum about how the menu bar on the right side was too easy to accidentally click when using the browser scroll bar (which is also on the right).
My suggestion to give an option to move that menu to the left side was ignored.
