From the Sharepoint team blog comes this post how to get a preview pane for viewing listitems in a list (which I've never seen before and is actually quite cool!) :
Create a new (contacts) list. (This is a good example since this list type has many columns by default.) On the List default view page, click Settings on the toolbar, and then click on Create View. Give the view a name and add all available columns. Scroll down to the Style section. Expand the section and select Preview Pane. Click OK. Hover over the list of items. Notice that as you hover each item, all info related to that item is displayed on the section to the right. The content of the preview pane appears in a similar fashion to the typical item display form. The end results looks similar to the following:
This is also not only handy for a contacts list but also for an Issue list, since you can very quickly scan the latest issues.
