Hello @ebb73, 'Buy for one year' will get you a Premium that expires after one year. With the 'Annual subscription' you are subscribed, Premium gets auto-renewed after one year.
Some users prefer not being subscribed.
Could you please specify what UI is unclear?
Location view can be saved in Settings - Start-up location.
Weather model cannot be saved, but thank you for suggestion.
What do you mean by "detail view of the location as an overlay"? Do you mean detailed forecast?
Alerts should be working with no issue. What kind of parameters did you select?
