Patreon-esque Subscription Payment
Add the option for users to be charged for all of their auto-renewing subscriptions on the first of the month (or another date of their choosing as Netflix allows). If cancelled after that date, would remain subscribed for the remainder of the month. New subscriptions would still be charged on the date of subscription. Could still track sub streak according to date of initial subscription.
100% agreed, plus it would save Twitch money in processing fees
