Sorry for my late review. I hope beta stage testing is not yet over... I've just been busy with my remote work.
First of all, Thank you for accepting me OP, sorry again for missing replying to your PM especially about confirming the received test funds.
To begin with the homepage, all I can say is perfect, I've checked each of the elements and I didn't find any issue. All links are working, but I just wonder why your Twitter account has been suspended.
Anyway, I completed the test escrow contract and it goes through well, from start to finish, I like the integration, synchronization of all the processes, and the concept specification.
I used two different web browsers for the separate buyer (Chrome) and seller (Firefox) Metamask accounts.
This escrow service contract is useful to dealers who most preferred the assurance.

The functionality is working perfectly, I didn't encounter errors aside from "Internal JSON-RPC error" after writing "Thank you" in the Contract completion message.

One more thing I noticed is the Notifications, I think it's confusing. The sort order is random. And the message text is not fully showing at least hovering the mouse on the desired item.
