That's okay for the documentation, but that can't be put on a checkbox or button of the wallet. For this we need good replacements for Darksend and/or InstantX. IMO InstantX is already quite good, I wouldn't replace it.
We could even have 2 or 3 separate subnetworks with different protocols.
You mean something like darksend trasactions would be in a different sidechain or something and recognizable by a merchant who could decide not to accept any premixed coins?
short and sweet
InstantX
PrivateX
that would have my vote
