Having just purchased the latest iteration of TV 4k (2nd Gen) I installed Pocketpedia TV. I like it from a stand point of browsing my Pedia's from my couch on my 50" screen.
Suggestion:
The Pedia selection screen be enabled to appear on each start-up of the App. At present if you close the App whilst still in a Pedia, that is where it will return to on next start-up, you then have to back out to change to another Pedia.
OR
Have all the sync'ed Pedia/s name/s appear across the top of the screen all the time, you just select from there.
