Little problem and question

First thing, awesome work. The plugin is just what i need for an idea. The only problem is that when i press annotate i get this message: “Oops, something went wrong. Please try again.” If i refresh the page i see the messages i posted… so is adding them. Could be some kind of jquery error?

On the other hand, is there a way to add some “marker” to the timeline so the users know where there are annotations?

Thanks in advance and excuse my english
