PROFILE MAXENTRIES

Use this to set the number of anime you want to see in each page of lists. This setting applies to the main anime list, your MyList, and search results.

If you set this value low enough then the "Next" button will no longer be displayed at the bottom of anime lists. At the time of this writing the cutoff seems to be less than 30. Presumably the devs assume that a list of less than 30 anime should fit on your screen all at once.
