When i start a search with an article open, the app will open on a new tab. I find this annoying, because eventually i'll get a lot of tabs open. I have to keep closing them periodically. When i search for a new subject, i'm no longer interested in the last an when i am i can open a new tab by myself. I think the default behavior should be to open the new article in the same tab or at least to have a setting that allowed that. It would also be more similar to the way mobile browsers (on Android) behave and thus a simpler to understand and more consistent experience across apps.

Thanks, I've added this our thread of tabs-related feedback.
