There are 2 things that I would like to ask.

First of all i want to add an extra tab and in there to insert an extra image. Just like the image uploader but for different use.

Second. Is there any plugin or extension that is saving in different table the extra fields data? I have created a search module based on the data inserted in extra fields. Can't get why you developed it this way.

Second - there isSherpa that "replaces" the extra fields
