Copy and paste controls into another app

[audrieg]

I would like to recreate an existing app because the app I made ended up full of junk items from trail and error. Is there an easy way to copy and paste from one app into another? It seems I can't open two instances of the desktop version at the same time.

I mean the PowerApps app for Windows (Store). For example, if you're in the web.powerapps.com portal, you can look at the apps and choose the Edit in Studio (Windows).

Hope this helps!
