In the Donation Form Designer, under Form --> Edit Gift Options, we are provided the option to add a description to a one time or recurring gift amount, but once saved and closed, this description is not visible in the form preview.
So, I'm assuming it's a useless feature for now, but it would extremely helpful for us as we are planning to create a giving society and want to add descriptions so that our donors can select a gift amount based on their desired giving level.
