I have no idea if this would be wanted or doable (from within cutetube or in another app). Say you have a 5 part series you want to download 50 min total in 5 10 minute parts. Abilty to cutejoin all the downloaded mp4 files into one file with a user designated name (ie instead of bla part 1, bla part 2, just bla. that way you could reconstruct movies. probably not doable right?
