I wrote a little browser extension to clean up the comment area of route pages by moving comments that are links to videos to a new video gallery, just below the photos. It also makes it a bit easier to peruse beta videos for boulder problems. Additionally there is a option to fully hide the videos/comments if you wish.
This is in a beta stage at this point. It currently it only works for links to YouTube videos.
A new version is available on Firefox. It adds compatibility for Firefox for Android. Additionally you can now choose to fully hide the comments rather than move them to a video gallery. You can enable this from the extensions options.
