Thanks @sonjathegrey@mstdn.party You are absolutely right and I have upvoted the feature request in Github, but honestly I don't see it as a big problem. If a hashtag brings too much undesired content to my feed, I can always unfollow it, and if it does not bring anything, it cannot bother me. So I think I can peacefully wait for very long for this feature. Having the ability to follow tags it is a great help though, so I am very grateful and happy that it has been finally added 😃
