When you load more than one...anything...but let's focus on videos...there is no option on the items you are loading to abort the loading individually.  If, you blindly dump three of them into a group, If it's too big, it won't TELL you it's too big, it'll just load FOREVER.  The twist is that the ones in the group you dumped that were an acceptable size WILL load, but then you need to get rid of ALL of them if you want the endless loading to stop.  Why can't there be an option on each video in the process of loading that could abort the process without affecting other videos that are being loaded?
