Maybe I'm insane, but if I want to go somewhere, wouldn't it make more sense to have handynotes on the portal destinations with the note being from which locations you can go get there, instead of the other way around?

Could you please give me an example? I think I have not understood this request.

Suppose for some reason I need to go to location X, let's say Bel'ameth in Dragon Isles. Now, it would make sense to be able to look at the Bel'ameth zone map in game and see handynotes that tell me FROM WHERE I can take a portal TO this location. Instead of having to hover over notes to find one that goes to Bel'ameth. So basically reverse notes from the ones that currently exist that exist at the destination point rather than at the departure point
