Design adjustments on the forum

Adjusted some of the forum design with a more custom theming:

  • Rounded off the buttons and elements like on the website
  • Replace the orange highlight color with blue
  • Subcategories always have the same color as the main category for simplicity
  • Adjusted category sorting
  • Did not add the plussy background as it’s very busy and it’s a symbol we wanted to phase out (?)

Anything else that should be corrected? @max.mehl @eal @bjoern @nikos others? :slight_smile:
