This is a great little plugin - when it works. I installed it and it was fading in and out going through post titles using the shortcode on a page. I changed the display type from "ID" to "rand" to have random posts come up, and it stopped working.
I have uninstalled it and re-installed it and since uninstalling does not clear out the database, all of those settings remain in there, so if I set a combination that breaks something, I'll never know what that is.
Also, the admin page is not fully documented so I don't know what many of the settings are.
Again, this is a great idea - I just wish it worked! For now, I have had to un-install it because it just displays one static post title.
