First I'd like to say that this is a great plug in and seems to bypass that annoying embed code issue with Youtube. I highly recommend it as an alternative to Oxwall's native attachment function. It installed and runs without a hitch so far :)
One thing that puzzles me is that unlike the example shown in your plug in preview..when I access the setting via my admin panel I do not see an option for enabling or disabling links. Only Videos and Photos.
It isn't a big deal but I was curious if that impacts some of the plugin's functionality. Is this omission caused by something on my end?
