View multiple QRs in shot

[Noitarud]

Suppose you have a list of QRs and you move down them to locate the right ones (can call it "QR vision"). At least support two columns and two rows. Colour the text windows / frame of ones that have been acted on or 'checked' (instead of blocking as others have thought, since you may change your mind). They all may be a larger document serialised into multiple installments.
