So, not to get too off-topic in your thread but, doesn't Counterwallet take care of the required/provided fee situation i.e are people tweaking things without knowing the impact or... are they trying to minimize fees and the wallet can't handle all of those cases?
I think most people aren't tweaking things because they don't know what they mean (but it could be checked of course, by looking at BTC Sell orders, especially expired).
Matches aren't handled in the wallet but below in counterpartyd (which is why counterpartyd can still use BTC Sell although it was recently removed from Counterwallet).
