fails if you have lots of authors

Stunned by how bad the usability is for such a popular plugin. If you have a lot of members, it will try to list out all your members and provide a widget for each one so you can assign imported content to authors. Problem is this takes so long if you have many members that you will need to adjust your PHP timeout. Dreadfully slow, poorly thought out. No option to just enter a username or UID instead of waiting for the entire list of members to load (SLOOOOOOWWWWLLLLYYYY).
