What would the benefit be of using the IconView instead of the ListView?  If we used a TreeView we could support grouping, folders and media clips.  Let me elaborate on media clips because its not a very good term.  Annodexing enables the definition of clips within one continuous media file.  When these files are imported pitivi should make the whole file available with the individual clips as children.

Should we forget about this?

No, I would personally like to be able have a "gallery" view (icon view using thumbnails). The reason is very simple: you can fit more of them since they wrap around horizontally. Of course, the icon view would have much less features than the list view, but that's expected.
