Love the new donation/tip feature being built in, thanks to Ghost developers for providing this.
I find myself wishing that the Donation option was included on the “Portal” page and could be customized from the checklist similar to how Tiers are chosen in the “Customize Portal” settings.
Currently, you have to provide two different links - one for membership, one for donation. Ideally I would present the users with a single link that showed subscription tiers alongside a Donate option so that they consider one time payment vs ongoing subscription (or free newsletter).
