Sync is a complicated procedure and in the future it would be nice to slowly remove the user from having to intervene. But as you mention above, the user is needed in a lot of cases like the "are you sure you want to delete" message that appears if Pocketpedia is trying to remove an item via sync. iOS is also limited and it's unlikely that Pocketpedia would be running if the users does not specifically lunch it to begin the sync.
Could not all this sync'ing be done via an iCloud function automatically in the background. I use an App called SoundHound which does this with its bookmark function. I make a bookmark on one iDevice and it updates all iDevices, this of course would extend to iMac's and laptops in the pedia's case.
Anyway just a thought.
