Introduced in Eudora 6.0, Content Concentrator makes it easy to get at the heart of an email conversation by making nearly the whole thread visible at a glance and removing redundant content.

In Eudora 6.1, Content Concentrator was made even more effective thanks to a profile control which offers users a pull down menu of three concentration levels - None, Compact, or Terse. Conveniently located directly above the preview pane, the profile control allows users to streamline or expand their view of an email thread on the fly.
