As Litecoin continues to split from Bitcoin, being the first (major) coin to add Segwit, the first to get the live lightning network, and soon to get Confidential Transaction, now, Litecoin must differentiate it's UI.
Bitcoin Core is an ugly client. Recent updates have only made it more clunky. 
Please be aware this is just a design proposal. It is not in Litecoin Core yet.
Here is the new Lightning network page. The client is available in both a light and dark theme. It's beautiful, showing graphs of your recent transactions, showing them in a nice flexible way instead of just a single list.
A new splash screen lets users know what's new in this version. (Confidential Transactions is not yet implemented, this is purely a design proposal!)
Here is the sending page. Designed to integrate seamlessly with Lightning, with modern rounded text boxes, clean fonts, and a great colour scheme.
