Right now, the only option with gifts partially funded is to 'abort'. But sometimes I get regular donations on stream, which means I can afford to buy the rest of the gift with my own money.
It would be nice to have a 'complete gift funding' option to have the gift be 'gifted' before it's fully funded, so that you can have control of when you get the money, the people who funded still get showcased in the gifts page, and you can get the gift yourself!
Note: obviously this would only apply to Payout gifts, not shipped ones.
