I would appreciate support for the control of the PLEX media server.
This open media server solution is well documented and supports Two-Way IP control.
It would be great to browse the media catalog (audio and/or video) and see all the information and artwork. Then being able to choose to start playback on the selected device and then being able to scroll the playback and see the cover/poster art.
