Just installed a neat little modification to the forum. It's called "MessagePreviewOnHover."
With this installed, you can get a quick preview of a post by "hovering" over it with your mouse pointer. It does not change any other functionality of the forum.
Here are the steps for using this feature:
1. Go into any board to read posts, just as you would normally do.
2. Without clicking on a post, just let your mouse pointer hover over it.
3. In a moment, a "preview" appears in a box on the screen, showing the first 124 characters of a post. The preview remains on the screen for about 5 seconds.
The screen shot below illustrates what the feature looks like for the current post:
