 description: >-
   Easy to use. The focus lies on both anticipating what users may need to do and ensuring that the user interface contains elements that are easily accessible, understandable, and user-friendly to make those actions easier.
 
   Always one step ahead. We work closely with developers of other projects so that functions can already be implemented early on.
 
   100% open source. Anyone can join, anyone can contribute.
