Without this addon i can't find option: "open next to current"
I presume there's no such option in opera 42.

All of help which I can find in google refers to opera 12 or 2x.
I have to say - it's annoying as hell.
Why new released product has help instructions from .... i presume year or a couple of years ago (opera 12?!?!! Please!!! Double facepalm).

Return to subject: Why in the name of the highest (regards of someones believes), there's no such thing in option.
"open new tab next to current".
It's one of the simplest, needed, and primary option!??!!

I realy don't know why they put options in previous versions, and in a new ones someone says: let's kick these options out - it's unnecessary

/Best Regards
