I'd transfer everything except what you're sending to a different wallet, then resubmit. Can't hurt you by double sending then

I don't think that makes much sense, when I could cancel transaction now :) it should be fine, it's all under the "signer" page

oooh when I look under the "signer" tab, the transaction is all there (has an edit and cancel option even), so I think I should be fine xD could have saved the trouble for you if I just clicked around like I was going mad
