Keeping default view and creating customize UI at the same time

I would like to customize frontend, taking control of UI. But default view is quite nice, whenever I add a new integration, it adds all cards automatically, I wouldn’t know that there are this kind of cards. For example I just added alexa integration and it shows even volume control, it’s so cool.
So my question is, is it possible to keep this auto-managed UI and create my own customize UI?
Second UI, default view tab etc?
Thanks in advance.
