I'm using Tusky, I switched to it some months ago from the official Mastodon app; but I don't remember exactly the missing feature that forced me to switch ahahah
Anyway I am really liking Tusky, it looks modern, clean, fast and personally I did not find any relevant bugs in it.
I just started this series this year by picking up Going Postal, which I finished something like a month ago. I liked it a lot and as my "gateway drug" into the Discworld, I think I will always have good memories of it.
Pop_OS on both laptop and desktop, since it has integrated nvidia graphic drivers and handles them without too much hassle. Before switching to Pop_OS I used to use Fedora for many years.
Yup, I think you can do that on Tusky by clicking on the human avatar with the plus icon on the right corner of this picture (you can also silence topics with other buttons)
