What about making a text editor that you can write down things to remeber? This would be an extended text editor that supports the hyperlinking used in the chat today.
If it was possible to drop a reference to a player into the editor (creates a link) and any other item it would be great.
For exploreres, make a shortcut that will paste in the current zone and coordinates, also as a link. When you click that link your map will open and show the location.
An easy way to drop this info to the chatbar whould also be cool :-)
This idea will not give content to gameplay, so i guess this is something that can wait. It was an idea anyway.
