No, I only simulated the same behaviour like tidy pics had. (I'm not shure, if this has changed already)
One problem with multi-upload: This is multi threaded, therefore you can't control, when the image upload is ready. To display the images in the correct order, either tidy should have a feature to reorder images - or we have to use the exif data of the image (if available). I implemented this at least into my slideshow, I'm not shure if this is implemented in the current life Version of tidy.

another version for multiupload would be the option to upload zip files...

if you need someone to test it I would love to! :) do you have a release date set?
