Backwards-Function on profile leading back to user overview
If you are starting at the profile overview of the employees and you click one, the profile opens. In case you would like to check other profiles as well, you have to click again on the colleague sign. In the mobile version this colleague sign is hidden in the menu, so that the menu needs to opened before the colleague button can be used.
This issue could be solved by installing a "To colleague overview"-Button which leads directly back to the page on which all colleagues are listed.
