i worked with all versions of LR since the release and this thing has always been a major problem (probably a bug).
it's highly annoying and intrusive, if it is not a bug i can't even understand the point of that pathetic ornament on a working software.
viewing in develop mode is not a solution. i find impossible to review a huge collections in develop mode and the survey mode doesn't even work on develop. if you click N on develop you go back to the library with that stupid white border. it doesn't solve the problem.
anyway... since this is a huge problem since the release of LR, isn't there any plugin around able to fix this?
