As far as I can see it for now, there needs to be a solution for LTC multipool mining.
I saw it a few times now that I mine LTC for hours, actual mining has over 460.000 shares, but no unconfirmed balances - the confirmed ones haven't changed either

That's a waste of resources for our side because we could have made money with the second best coin meanwhile.
EDIT:
If other users see it the same, a solution could be to move LTC out of the multipool.
