i confirm the delay of highlight Text in the new PDF Reader, the old PDF Reader ist faster for text-highlighting but the old one got the annoying automatic pop up window to enter comments, which the new pdf reader didnt have - only if i explicit touch the highlighted Text, which is defenitively a better solution.
and the feature to add underline text would be a nice addition for the notice-tools, to have both, underline text and highlight text, as well as strike out text like the android relipgo reader has.
to strike out text is as well an usefull learning-technique to actively strike out the unimportant parts of an paragraph, hence to visualize the remaining important parts to learn.
