What I like most about this add-on's display of new posts is that it actually shows content from the posts themselves. However, I wish to control the amount of text shown and wonder if that can be expanded. Also, would it be an easy matter to have this new posts box displayed wider and above the forum listing instead of as a sidebar block? With the box aligned that way, more text would not cause it to stretch down much more since there is more horizontal space, and by being above the forum listing it would be more immediately visible to the guest I suppose.
If you are wondering what I am getting at, here is a screen shot I took of a similar feature when my forum was still using vBulletin 3.x:
http://xenforo.com/community/threads/nexias-newscast-existing-vb3-add-on.8651/ As you can see, that add-on displayed content from the latest topics, whereas yours displays from latest content in general. That distinction does not matter so much to me, though, since what is important is that it displays actual words/content being posted on the forum rather than just the title, so that guests may get a taste of the latest content before having to browse the forums/click topic titles.
Moreover, that add-on, like yours, allows the administrator to choose how many new topics (posts in your case) to display, though it also allows you to control the amount of characters to display from the posts themselves, and to exclude certain forums.
Anyways, the alignment of the box widened above the forum listing and the ability to control the amount of characters is what is of most interest to me, though the ability to specify just new topics would be cool too. I wonder how much that would cost as a paid add-on, if this is not an easy add-on to make.
