arde
i know light wallet phone apps are for common people. but i wouldnt be to rushing into "just works"
the full decentralised desktop nodes will tinker with the code and change opcodes and other things to gain the upper hand of transactions. so it is still best to have a feature where users can see what they are signing(rax tx) rather than just have everything on autopilot/auto accept

even if we totally forget about bugs, changing opcodes. .. and just think about the auto accept/autopilot of routing funds...
