Is there a way or can we generate a way to optionally close the open tab automatically as we open another favorite instead of the extra step of closing the tab that we're finished with?
that's just doesn't do it. i have the setting checked but still opens in a new tab and have to manually close the old one
apologies. if u leave the old tab open, switch back to the main tab where the feed is, and click on a link it will open it in the 2nd (already opened tab)
