I have same problem.

I made an example because happen always... every time I need delete a folder I have to stay on the screen and wait because FTP disconnect and stop the deletion leaving incomplete the deletion and folder still exist.

Is a not good workflow for me.

It's not a bug. Deleting is not supposed to resume.

But if more people ask for this, we may implement it.
