MultiLite is a lightweight Java client based on MultiBit (And bitcoinj). It is open source and includes all the same features a multibit user would expect. I haven't been able to test this as much as I would like so it's probably best not to store large amounts of LTC.
Some Features:
- Open source
- Checkpoints allow a user to sync and start sending LTC in a matter of minutes
- Uses the same nodes as the official client
- Converts LTC to variours Fiat rates (AUD, USD, EUR etc)
- Import private keys from the Core client
- Low footprint (Doesn't use alot of resources)
- 100% Based on Multibit
- Runs on Windows, OSX and Linux
