Starting With Mobile

Hello Everyone,

I am looking to start building with the Native Mobile App & PWA Kit. In the end my goal is to launch an app on the app store (Native). My question is when I open the template in bubble it is hard for me to get a bearing for what I am editing. When I preview this is what i see.

Is there some way I can have like a frame that fits the size of the app? So I can better see and layout the pages I am editing?

Currently hard to see what I am editing.
