By leveraging controls, you can provide the user experience that best reflects what you want to deliver.

How can you allow users to have greater access?

Every member of a security group has the same permission for an app as the overall group does. However, you can specify greater permissions for one or more members of that group to allow them greater access. For example, you can give Security Group A permission to run an app, but you can also give User B, who belongs to that group, Co-owner permission. Every member of the security group can run the app, but only User B can edit it. If you give Security Group A Co-owner permission and User B permission to run the app, User B can still edit the app.

What's a filter?

Filter - This function is often used with galleries or tables of data to narrow down the rows returned from your data source. You do this by specifying one or more columns in your data set to perform a logic test on, which will allow you to return data that falls in a certain date range, has a set value, or was created by the user for example.

The various actions performed with forms are controlled by form modes allowing the form to serve many purposes.

What are Functions? (Power Fx)

No complicated code is necessary, simply powerful functions with straightforward inputs to enhance your app.
