Dargo, regarding the recent BTC/ETH switch to ETH/BTC. I believe if you would do the same for LTC to make it LTC/BTC it would help with the volume on that pair. I would consider that as a good step. You can always check people who traded LTC in last months and send them a poll. I think they will be happy about the switch, and you should be happy about higher volume.
Cheers
