Optimize UI

[pstackebrandt]

• Design is too big/"zoomed in", I tend to zoom out to get a better overview (from 100 to 75%)
• Portrait sometimes too big (impl. v1.12.0)

Background

UI is very simple, looks not professional

Portrait too big if one decreases windows width to small screen. Font scales, image not.
Portrait seems to scale down correctly on phones.
