They should add these two as default enabled:
Anti-Adblock Reek
I don't care about cookies
I hate pages bitching about me using Adblock and the stupid "no purpose" cookie popups also need to go (yeah, we get it, ALL webpage use stupid cookies, no need to tell us the obvious). These two are a must have that everyone should get.
Fanboy's Tracking list and Enhanced anti tracking and Annoyances as optional selection, but certainly not bunch of others which are useless, especially Malware domains which are just a bloat of outdated links. Pointless waste of CPU resources combing through for relevant hits. The rest is already in Opera.
