For a global view of all proposals and orders you created, go to the History and Catch Up tabs on the dashboard.
The History tab displays a nice view of all proposals and orders. Both proposals and orders can be sorted by latest or oldest and filtered by status.
Proposal/Order notes are visible and you can add new notes, mention other users, filter by unseen mentions, and change proposal/order status easily.
The Catch-Up tab displays recent activities and mentions. Here you can see who and when changed Proposal or Order status, as well as notes where they were mentioned.
