My preference is to have the sidebar switched off but this means that to get, for example, to the home screen you have to do 2 clicks – one to bring up the sidebar and one to select home. There’s plenty of space at the top of the screen to add some icons – here’s an example (I’m sure that the Roon team could design better icons) showing what it might look like with icons for Home, Albums and Artists. Ideally, make this configurable in settings so that users could have icons for their most common selections in this area of the screen.
I would not see this as essential - but nice to have: yes certainly
