I am looking forward to those improvements. I guess the calculations for fees are really off. You can discourage spam without charging 10% fees on a 1 LTC transaction. The current fee structure makes the coin unfriendly to actual users.
I have changed pool settings to have less transactions per amount of LTC. I am sure this will help some.
I didn't design the fee structure. I am just stating how things are now.
Generally, you pay more if you are impatient. You pay less (or even free) if you are more patient.
This will be a little better in 0.8.x but the details haven't been worked out yet.
