sort by last modified date

Hi! So far I am loving this plugin. I’ll be sure my client chips in. ??

I am perplexed…In the description of the things the plugin does, it says: “Allows you to sort posts/pages in last updated/modified date-time order.” This is the main reason I installed this plugin.

I can’t figure out where to do this. Please advise. Thanks!
