The idea is to add the possibility to create templates for the frames we create. Now, we only have a selction of sizes when we select the frame tool, but what if we could also include some other properties, like frames inside, layout grids, etc. This would make it easy to create subsequent pages inside an app or website that already has some static elements which will appear on every page, like a sidebar for a desktop app, or a status bar for anything on mobile.
I believe that this feature would take out a lot of repetition from the designers’ daily workflow and allow for more consistency and speed when creating complex products.
