Creating basic apps in PowerApps is decievingly simple, but once we start taking them to users for feedback the special cases require some complex programming. Developing and manipulating collections and variables is very time consuming when you have to constantly switch back and forth the the collections and variables screen to verify your naming and results or create temporary output tables to see logic effects real-time. PowerApps should allow the ability to pop the collections and variables lists out into a second window to match industry standard IDE expirience.
