Needed some time to get used to it but I really like @MonaApp 's approach to discovery. A single tab gets you to a certain instance where you then can switch between all its feeds on a second layer. Thus the tree icon. 🌳💚
The only thing I am missing is seeing the hashtag results of the chosen instance. Right now choosing a trending hashtag from a remote instance shows me the hashtag feed of my home instance. Which always leads to the same results.
