Display Option – Numbers of Task Lists per Page
You can adjust the number of Task Lists you want to display on your project Task Lists view.
The default value is 15 Task Lists per page but you can change this to anything between 5 and 30.
We offer you this option because higher numbers of lists displaying on your screen require more data to be loaded into your browser and may result in performance problems on lower specification systems or older browsers.
You can adjust this in your Account Settings > Look and Feel section
