**How to reproduce**
Log in and load start screen (In-box).
{F2430440}
**Actual behaviour**
No easily accessible compose-new-email-button is being shown on the start screen. To compose a new email, the user has to find the feature in a submenu. (Same problem in 'Contact' interface --> no button "create new contact")
{F2430443}
**Expected behaviour**
As composing new emails is the core feature of an email-client, the user expects a centrally located and easily accessible compose-new-email-feature on the start-screen of the programm.
** Example**
This is the start screen of the GMX-mobile-app. The "compose new email"-button is located in the lower right hand corner of the screen.
