What I am sometimes missing is the ability to jump back to the start of the first track of the queue with one click. The “back” button is disabled because there is no previous track. The mini player offers no option at all. The NP screen has the “10s back” button, which you have to click multiple times if you are more than 10 seconds into the track. And finally you can go into the queue and click on the first track, but that is already three clicks away (open NP, open queue, click first track).
I guess most players leave the “back” button always active. Would that be an option? The behaviour of the button would then change depending on the presence of a previous track…
