[Plugin: Ambrosite Next/Previous Post Link Plus] Varying num_results

In order to do this, I would have to query the database twice, since the number of next posts is not known until after the query is run, and that information is needed to get the correct number of previous posts. I probably would not add this feature into the plugin, since it would double the execution time and increase the load on the database. If you want to contract me to write custom code for you, contact me off-forum.
