This is a simple plugin which displays a specified number of characters from the first post of a thread, in the forum display page, or search pages. The "preview" is displayed as a tooltip, when the user hovers his/her mouse over the thread.

You can change the length of the preview which is displayed in the AdminCP settings.

This plugin preparses the preview to lower server resource use.


NOTE: When you activate the plugin, all thread messages will be preparsed/cached. For larger boards with lots of threads, this process may take a while.
