Litecoin is not moving forward for now except in it's price and this is because we would see begin to see a bull run in the price of bitcoin which will affect all other coins in the market, especially those coins that have large market volumes and have a real life value in the crypto sphere, apart from this I don't think there is a major problem litecoin is solving since it's just a fork of bitcoin and bitcoin node already has all of it's feature including lightning network, which was the major feature of litecoin that they could brag about in the past, they have to come up with something new to become relevant.
