Interface Change for Managing the Beacon
I suggest the following change to the interface:
When clicking on your beacon on the world map, you don't get asked about managing your beacon, you just travel there.
To remove the beacon there could be the following two methods:
Add an entry into the menu where you find the command to set a beacon, right under it.
Add a button in the right bottom corner of the world menu, i.e. an icon resembling the beacon, stricken trough.

I don't care how it is handled, just so we have an option to skip the confirmation.What's the point of removing the beacon anyway... except to have something to confirm? And why would we need a confirm, "oops wow I clicked the beacon and was warped to it" does not seem bad for a new player.
