Opening a New Tab to your Homepage on an iPad:

This is not an option as of this reply. So, recommend to Apple that they make this an option. Apple wount get back to you directly, but the more feedback they revise on this, the more they will know what their customers prefer and what options to include in iPadOS versions to come.
