No reply on the name issue yet, but I got a tip from David about using two apps in split screen. Should work in all Android versions from 6 upward.
Just two examples,
Peanut + Dashboard
Peanut + Sota Spotter
And if you click the small line in the middle, three more options pop up
First one is for making a shortcut on your start screen, so next time you want to use the same apps in split, just click the shortcut.
The middle icon is for swapping the apps.
The bottom one is for ending the split mode.
If you have never used this split mode, there are videos on YouTube showing how to do it, look for one that uses your Android version.
