I also don't have any synchronization between my desktop Opera on Windows and my Opera for Android. Both are the latest versions and on both I am logged in.
Admittedly I don't use the mobile version often and I even don't see any possibility to manage bookmarks there.

You missed the obvious. Opera will import settings and passwords from your default browser.

I'm no expert but could anybody please confirm or (as I'm hoping) denying this statement.

Even when accepting that stored passwords in a browser can not be considered save I mean what's the logic that a new installed program is allowed to import passwords from another rather unrelated program?

Opera 12.17 still one of my favorite and will always be, but now I love Opera 28 even more!
Thank you Opera people.

I would be very interested what properties of 12.17 you liked so much that is was your favorite browser and what properties you like even more in the new Opera.

I suppose they will make the tabs stacking. To many people want it.
So be of good thoughts.

I hope you are right.
I'm also in for "Tab Stacking" as one of the painfully missing features for me.

Huge arrow and black spot? Are you certain that is not a setting in your mouse (if you're using a mouse)? I don't see this.

Yes I'm certain.
Checking "for mouse wheel clicks" and immediately a rather big arrow appears after a mid-click pointing to the direction of the mouse movement. Increasing the movement (= increasing speed) additionally a black spot appears in a distance to the arrow proportional to the speed.

Here's a screenshot but the black spot (about the same diameter as the arrow) seems not to be "screenshotable"

Thanks so much for recommending "modern scroll".
Works great.
But so far I haven't found a setting to minimize the huge arrow and black spot during scrolling.

I'm trying to get used to the new Opera since browsing experiences under Presto is getting more and more cumbersome.

I'm too missing the versatile Bookmark features of Presto.....

Thanks for the link.

I was looking for a different problem regarding scrolling which I hoped to solve using these commands.

The slowest scroll speed is a bit to fast for my preference. In Presto it was possible to scroll really slow. I'm speaking of pressing the middle-mouse-key and controlling the scroll speed by moving the mouse up and down.

Does anybody know if this can be achieved by these commands or other means?
