Set the Default Sort Order for Apps

As a Salesforce admin, you control the initial sort order of the Salesforce standard, custom, and connected apps that your users see in your org. You can also hide apps so that they don’t show in the App Launcher.
Available in: both Lightning Experience and Salesforce Classic
Available in: Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

Users can rearrange the apps in their App Launcher to their liking. Their sort order overrides yours.

Apps in the App Launcher appear as large tiles and link to Salesforce standard apps, custom apps, and connected apps. Connected apps are third-party apps, such as Google’s G Suite, that you install for your users’ convenience. By installing connected apps, your users can access them from one place and without having to log in again.

To make connected apps and service providers appear in the App Launcher, specify their start URL in the App Manager. The start URL takes users to a specific location after authenticating.
