Hi Erik,
You can actually create a new System View to sort by either Active or Inactive. In fact you can sort by a long list of criteria that you choose. To do so, Click on the ellipses (...) at the top of the screen and select New System View then click on View Properties and give it a name such as "Active Landing Pages" and click OK. Next, you're going to click on Edit Filter Criteria and set the criteria to Status | Equals | Active and click OK. Don't forget to hit save and then you can close the window and your new view will show up under the drop down list at the top.
Hope this helps.
