Remove 'Save as...' option for saving torrc
If there's one thing I've learned after years of hearing from arm users it's
that unnecessary options only breeds confusion. Why would someone want to
persist their configuration to a different location? Could happen, but doubt an
arm user's ever done it.
Kinda impressed how much code went into supporting that. :P
