Hi - at the moment you can't manually delete a location.
But older locations will be dropped automatically when you add new ones.
The new ones will be added to the top of your list.
This way you can organize the locations.
In the next version I'll add a function to delete locations and organize them more easily. But for now you'll have to use the above workaround.
cheers
