History Navigation Mode 3
This was a killer Opera 12 setting, that let you browse back/forth in blazing fast speed, loading the pages from cache, ignoring server changes etc. I wonder if we can see such thing in Vivaldi. If it's even possible with this Blink engine. (still in love with Presto, the best thing ever happened to the web)
This feature is already in bugtracker as VB-4078 "History Navigation Mode"
I dont know if there is much time for the Vivaldi devs to do this quickly or in next months.
And in Chromium browser it is a wish for faster loading, too. But it is not implemented yet.
Let us wait and hope.
