Could you make that feature available for other boards too?

This came to my mind when i was lurking around a few boards (market, art and discussion). It's pretty stressful to open two tabs, one for the first page (containing the stuff being sold or other info.) and the other one to accompany the offers or whatever interests you in the posterior pages.. I know that this isn't a revolutionary suggestion, but it would be nice to have that little feature on other boards too, or at least making it an optional feature.
