Hi Denise,
It is true that you can use the split view or multitasking function of your device to work with two apps at the same time. However, you may only do this with 2 different apps most of the time. For example, a Word document and an Excel file. Please note
that the said function is from your device and not from the applications that you are using.
I'd recommend contacting your devices' support team to help you out with the information on where you can possibly send this feedback as an innovative idea that they may incorporate in their future updates.
If you have additional questions, please let me know by replying to this thread. This way, I'll get notified and respond back to you as soon as I can.
