CompactView
CompactView allows you to display any Website in a small windows on top of anything else, like a picture in picture.
CompactView is a Windows 10 UWP that allows you to have any Website as Picture in Picture. Unfortunatly I am unable to submit screenshots that: "Also, please re-submit the app and use screenshots that are direct captures of the Windows app and accurately show what the app does.", therefore the App is no longer in the store.
