Learn how to minimize controls in your app by using only 1 form, and only 1 gallery, for multiple SharePoint Lists in this week's Friday Functions video.
This is relevant when all the list columns are identical. For example, imagine you are publishing an app for 5 departments, where they are each submitting the same requests to a SharePoint site collection dedicated to their department.
Benefits: A. Minimize controls, B. No need to have duplicate apps for each department, C. Reduces the number of items in each list (so that you reach delegation limits less quickly), and D. If really 1 site per department; permission things using the Office 365 Users Department Property
Note: If permissions are different, please leverage the DataSourceInfo() and/or IsError() functions to trap the users permissions when all data sources are in the app, AND only use one connector instance for all SharePoint lists. Be careful taking this approach across international regions as the rule is to keep apps, and data in the same environment/region where your end users will be using them.
