OK, now I understand what you are looking for. If I am correct, you are looking for a Tool that will gather all of your Personal Cache Notes in a list summary by GC code and cache name that you can filter by cache type and also provide keyword search capabilities.
I believe you mean this area on the cache description page:
Personal Cache Note
Click to enter a note
Yes, this would be a very useful tool to help search for the following reasons:
- Puzzle solutions - add a note for future reference how you solved it.
- Parking way-points - I only use a GPS and not a smart phone.
- Cache find details - spoiler information not included in Found It logs.
- Coordinates - reference points
