You can view your sales for different periods of time, eg. last month, this month, last 30 days, etc. Be aware that it includes the item price plus the postage cost though. You can still see the last 60 days figure on the old Sold page in All Selling (without the postage).

To follow up on what was said about the shortcuts list on the overview page, you can insert the URL for any shortcuts you want on the list, and label them however you want them to appear on the list. You could easily put a link there to the Community page.
