Great Widget with few missing stuff

First of all I would like to thank the developer for this great Plugin.
I want to bring your attention to following that will make it more user friendly

1. There should be an option to duplicate a tab so that we dont have to start from the scratch fro each tab.
2. In the WYSIWYG Editor you have the option of text only, option for Visual should also be there.
3. When I try to add a media with the WYSIWYG Editor, the options to enter caption and alt text is not selectable.
