Yes, we plan to let you easily reorder your photos based on their location groups.
Yes, this is definitely in the works! Each location will have its own page where you can easily see all the stories for that location.
Thanks for the suggestion. We do have plans to improve the look of the location tiles. 
Not a silly question at all! It's something we are working to improve but currently the way to do it is to go to the story 'overview' mode. Click on "Set location" under "Options", then drag the photo into the trash can. Sorry, it's convoluted at the moment. 
That's a good idea. Let us think about it.
If the photo's location has been set, there will be a marker on the map to mark its location. You must have been looking at the map for a photo whose location is not set.
