User Duplication is near perfect

Good plugin! Why not 5 stars? My need to be able to copy a user is to have all the content, including custom fields, prefilled when I create a new user. Works great.
Unfortunately, the duplication creates a random user name, based on the source user, resulting in something like SourceUserName-2. In most cases this will not do. Now there are ways to change User Names but I feel this should be done in the duplication process. I hope you’ll think about that option!
