Although months ago a similar feature was introduced and a few days later it was removed, due to user dissatisfaction – it is back again as a “new” feature.
Moving between the defined algorithm of the “feed” and the timeline of the “tweets” of the people you follow, they will soon be possible to “swipe” according to the warnings of Elon Musk.
More active Twitter users probably remember March of last year when this feature was rolled out. The goal is to facilitate the transition between the two timelines among the newest and most popular “tweets”.
A few days later this function was removed due to the dissatisfaction of users, that Twitter constantly showed them “new tweets”, “tweets of people who do not follow them”.
However, now it is returning “as the new navigation”, and it remains to be seen what information the “returning” users will have and how much the “new function” will be supported this time.
