Another option that might be useful, is to is to create a pocket query with the Have Not Been Found option ticked. Good for chasing FTFs. Note that Pocket Queries do not have to have a date to be run selected, it will show on the Geocaching map without it.
Also as a premium member, you can get an email sent to you of newly published caches - see Set Up Notifications, on your Quickview page.
Lastly, to get a hidden date other than a week, you need to use Project-GC. Got Tools > Map Compare. Enter the area, select add filter, add the hidden date, enter the from date details, select None Found (new caches that you have not found). If you are a paid up member of PGC you can then add these to a virtual GPS, which allows you to easily create a GPX file.
