That's exactly what I was looking for, thanks

Great feature. I can see how this could be easily integrated into the various screens such as the Add Waypoints screen. Will bump it up in priority. 

This advanced filtering isn't something that is in the current version, but we are working on adding it in 2.1. You will be able to filter by a large number of parameters in Offline Lists.

The reason we don't support landscape is that it imposes additional UI layout challenges. I do realize there are advantages to having landscape, so it is something we are looking into as well as improved iPad support.

Another approach when logging is to enable the Save As Field Note option. You can then edit all your logs as field notes on the Geocaching.Com site vs directly uploading to the respective cache pages.

After you log a cache where it's not sent immediately, it will show under your pending logs list. At the bottom of the main window on the right is an icon for More. Click More and in the screen that opens is an option near the top for Pending Geocache Logs. When you click into that all your pending logs are displayed. You can edit any pending log by clicking it in the list. You can change it there from Found to Not Found. 
In the list of Pending Logs, if you slide one to the left in the list, you will see a standard iOS Delete option to completely remove the pending log.
I hope that helps.
