@Matt Campbell I took a look at more apps that have lists as their integral part. Audio player #amberol has a playlist where its list items would benefit from calculated accessible names. gnome-podcasts looks as if it's already doing what we need the items have all the text from their children. I haven't looked how they are doing it though. Various lists within the gnome control center would also benefit from the accessible name calculation as an alternative to setting accessible manually. For example list of wifi networks is missing state information and signal strength. List of bluetooth devices is missing the state information. List of apps under notifications is missing a status information. List of keyboard shortcuts is missing assigned shortcuts, only action names are part of the accessible name. List of printers has all the details including status, location, description. Actually this might be the only list I am surprised looks about right to me. Hmm, perhaps I shal try to collect all these comments and submit it as a GTK feature request as calculating the labels might really be helpfull it seems.

Congrats @gnome #Amberol is very #accessible music player! Player controls including volume and skip sliders, playlist view, playlist selection all these features can be used with keyboard alone and screen reader turned on. If GTK issues like inaccessible shortcuts window, role names part of the controls labels will get fixed in the future it would really become fully complete in terms of #a11y.
