Add third button to modal?

[greetclammy]

I wish there was a third button in the capture modal--"New"--that would act as "Ok" (save) and bring up a new modal. This would allow for rapid brain dumping. A quick mock-up:

Although, looking at it now, I'd like the new button to be sandwiched between "Cancel" and "Ok" instead.

Is there a way to achieve this?

P.S. I'd also like to rename the "Ok" button to "Save" but this is less important.
