Jaffasoft -
Great feedback. I think version 2.0 solves at least some of these requestions; you can use the [recreading] short code to embed the output into a page, and the options page gives you some unique control over this output.
In a future version, we'll add the ability to override the options page when calling the output by function in a template or by short code attributes (i.e. [recreading list="20" source="false"]).
The idea for a block below the list that would load a full item when the title is click is a neat one that we'll add to the desired features list.
You can accomplish something similar with some custom CSS right now. You could display none everything in the item except the title, and add a ":hover" state to the item's container that would display block all the hidden pieces. This would show the full item as users roll over the titles.
For future reference, we're much more responsive to comments over at our plugin's page on our website:
