Do you think this new version will allow you to define an area of interest on a recorded clip during playback, and then generate bookmarks anytime activity in that area is found in the clip? I don't recall which NVR I saw that had this feature but it was pretty slick. It allows you filter your clip AFTER it was recorded, and create thumbnails/bookmarks for time codes where the defined area sees activity.
It would really cut down on reviewing tons of video when you're really only interested in a small portion of the screen. I realize you can do this with target zones BEFORE you record, but it'd be neat to do it retroactively - especially on continuous recordings.
