You can now accept or reject a premise without opening the review. Select a premise on a published argument and two controls appear beside it: accept, if you grant the step it draws, or reject, if it doesn't follow. Either one asks you why, from the same list of reasons the review uses, and your decision stays on the premise afterwards so you can see it — or change your mind — the next time you read the argument. Rejecting says the step doesn't follow; it never says anything in the premise is false.

The controls stay out of the way until there is something to see. A premise you have not decided, on an argument you are only reading, shows nothing at all — they appear when you select the premise, when you have already decided it, or when a review you finished decided it. A premise that states something rather than drawing a step says so instead, so a premise with no controls doesn't read as one with a missing button.

Premises without a title can be selected now. Most premises have no title, and until now only titled ones could be picked — an untitled one shows "Supporting premise" or "Conclusion premise" in its place, and selecting it works like any other.
