I really like your plugin! It does almost exactly what I need.
I have a small feature request. Could you add a field to allow users to specify the text we want to appear in the drop-down menu? By default, it says “Select Author…”. I had to edit the plugin to manually remove the “…” so that the style would match the other drop-down menus in the same sidebar. (None of my other drop-downs use “…”.)
If you can support this option through a field, then I won’t have to modify the plugin again every time it’s updated. It’s a small thing, I realize, but it would be a big help since I plan to use your plugin on lots of websites!
