I like both of these ideas because I really dislike breaking my immersion with gathering to alt-tab out to a third party website.
The 1 hour spawn is still a problem due to the fact that HW zones are freakishly large. If I am down at Moghome even with flight capability I can't get up north fast enough to catch the Dravanian mistletoe node to know where it spawns. I can see on the mini-map that it's "up there". It can take successive spawns to find the right area.
Maybe at the very least having it appear on the normal map while it is up may help. You'll still miss that spawn cycle, but you will at least know where it spawns for the next one.
