No comment.
These bookmarks don't like me at all. Completely unmanageable. Yes, I can do the stuff you tell me, but no more.
I'm so sad, Opera is unrecognisable. :'''(

Explain me that, please:
what's the point of select some bookmarks if you can't do anything with this selection? For example: you can't open all the selected bookmarks in the same time or move all selected into another folder.
Lucky me Opera as improved bookmarks!

I totally agree.
New bookmarks are completely unmanageable.
If you want to make some order in your folder you need to move each single bookmarks step by step. And you can't add a comment on the bookmark.
Where the hell is gone the old easy to use side bar?
The side bar was the thing which makes Opera different. Here you found bookmarks, all the links in the page, even take notes!!! This cr... thing is just another bad copy of chrome or explorer (I hate both).
I use Opera since... it's long time I don't remember exactly, Opera has advertise or payment, but was centuries ahead. Opera created feature which are standard now.
I even could pay to have the feature I want.
I have a suggestion. Opera like it is for free. Special features by payment. 2€ for the old sidebar working good.
Think about it.
You can really make money!
My bookmarks are a lot and well organized by folder and sub-folders, so, please, do something about it for the new release. Now, I must to export bookmarks, import and manage they using iceweasel, export from icewasel, delete opera bookmarks and import bookmarks in Opera again. It works, but....

Greetings from Italy.

PS:
Other things I miss are:

• the "GO" button. What the hell have you guys against the "go" button?
• The "open with $otherbrowser" in context menu
• Identify as ... to mock website which don't recognize opera as browser
• the customizable bar where you put the buttons in you favourite order. Even add a "go" button.
• the status bar where you can activate/disactivate images or Opera turbo as you wish. I live in Italy where adsl sucks, if you are the lucky one having an adsl, and Opera, with this, saved my days when I still must use the 56k modem, while other people run with a 20Mb adsl (a couple km from me downtown, maybe is 3 km).
