UX audit: Landing page and navigation

[CJ-Rose]

1. Landing page content and readability:

• all sections can be better defined with alternating white and grey background as seen in first section

• update text to include all tokens available on a given network

• present items in a single column list for visual consistency with above section

• present items in a single column list for visual consistency with above section
• add screenshot to represent this feature

• update supported networks and tokens
• should note why ETH is not supported

• update to Kleros for default provider
• grammar correction: "How do arbitrations work" -or- "How does arbitration work"

2. Navigation:

• remove “Support” link -- navigation to new docs window is confusing
• add “About” link to nav bar

• “Documentation” link should navigate directly to docs main and not open in new window with another "home" page
• “Home” link should navigate back to landing page
• navigation to docs "landing page" is unnecessary
  • videos can be moved to landing page or eleminated
  • FAQ linking into docs topics from here is disorienting
