Wonderful plugin

I just wanted to thank the developer of this plugin for the excellent work.
I wish it would become part of WordPress core!

Thank you!

PS: I have only one wish: some kind of visual feedback while the attachment gets uploaded. Without that, it is difficult to know what is going on, and one may think the upload is not working, and unwillingly cancel the process.
