Thanks Jeremy! Most feedback are similar to the header feedback, except the image slot one is new.

Desktop Feedback
Logo Slot

• Update color to Base/border for the dash border line around "logo slot"
• Unbold the text "logo slot"
• The entire area of "logo slot / logo name / beta tag" should be linked to the home page of the product. Not sure if this affects the code

Tag

• Update text inside the tags to title case
• Remove the hover effect for the tags

Image slot

• each image should have a link to the designated home page of that logo
• Update the "person" minimal button to a icon button (see design for the specific spec)
