 This update provides some new features for the design. It also contains some improvements and I have also fixed some bugs.
 
 ## New features
+
 - The overview page now has the note column and is overall better organised
 - I also addded the regular header to the page
 - I have added three animations to the Borrow System
+- I have added a new icon for the frontend, which is now also used in the header and the favicon. It is a dark version of the old icon, which fits better to the overall design. I have made it with Icon Composer. The old icon is still used for the admin panel, which has a light design. (Maybe I will change the admin panel design in the future...)
