Using plugin v.0.1.2 this is an issue when you have manual folder ordering option.

Looks like only main folders are trashed. Child folders are not trashed. This will give you the message when you try to empty the trash.
Unless changing the ordering option something else than manual.
… but child folders are not visible anywhere, because the parent folder already trashed.

Maybe you are right … this is your plugin and you design the way you want:)

I managed to isolate the gallery images from the Media Library using a wordpress core filter.
(using WordPress 3.5.1, plugin version 0.1.2)

See the code bellow. Can you help me to point out how can I isolate the folder images from the insert media popup box?
I’m new in that one, and I’m sure without help I can figure out in a few days, but though you could give me some hints.

Deleting folders on FTP has the same problem.
The associated folder post will be trashed.
But
– there is no way to restore from the trash
– media library full of broken images, and you have to spend a lot of time to cleanup the media section

This is a fact feedback, not a complain:)
Sorry if you see differently. Some people will not take any effort to submit an issue, suggestions, improvements … and they move on. But I’m still here and try to help you.
