with regards to the scrollbar default/lowlight elements
if it's not too difficult could you please implement
<element id="ScrollBarBorderNarrowOnly">true</element>
so if you have
<element id="ScrollbarNoArrows">true</element> active
the border attribute will only show when narrow scrollbars are used
for podcasts you have already added
<element id="Controls.SubscriptionCounter" bg="xxx,xxx,xxx" fg="xxx,xxx,xxx" />
<element id="Controls.EpisodeNotPlayed bg="xxx,xxx,xxx" />
would <element id="Controls.EpisodeDownloading" bg="xxx,xxx,xxx" />
be possible for the little blue arrow in front of the episode/s that is downloading
