Welcome to Roon, @Vondy 
In Roon, you’ve got a visually enriched Artist Browser for which @ged_hickman1 posted a screenshot but there’s no “boring” and simple artist list. Roon does things differently than other music software and IMHO for good reasons. Take some time to get used to how Roon works and it’s very likely that you’ll appreciate it soon.
In case you still miss a plain “old” artist list: have look at this topic: List view when browsing artists – you might find some additional hints on how to efficiently use the Artist Browser to achieve things. Or you could add to the feature request why it’s actually and really really needed.
