Improve Waitlist Functionality

Just joined OTF so new to app. Suggested improvement to waitlist functionality - option notify user each time they move up a spot on the waitlist and notify when a spot is available with a confirmation to accept the spot or let it go.
Would also like an option to add classes to my iPhone calendar (during booking or after the fact)
