Batch Move and Deletion

We had offers a BatchMove and BatchDeletion plugin to this community, and We get the answer “Also, you can already batch move posts into categories via the posts page. What extra functionality is this adding?”

We have decided to take or WordPress BatchMove plug-in out the public domain.

Is there some who can tell witch plug-in or functionality that is and where We can find that, We have develop our plug-in because we could not find a batch Remove in WordPress. A batch Add is there, but if you did make a mistake you had a lot of work to correct that.
On the Internet I find more people with the same problem, are we stupid?

After all its much better when it was solid implemented in WordPress self.
I hoop there is someone who knows the answer.
