How Has This Been Tested?

Awaiting final confirmation on copy/styles before merge

@L03TJ3 i'm not sure you are reseting the modal state. ie would it open again on a second tx?

[L03TJ3]

@sirpy good catch and no, my last test showed it did not

Will be fixed along with the final suggestions on copy's/style
