One vertical scrollbar may be a somewhat different request anyway ... in old (Presto-based) Opera there were two different options referred to as Tiled and Linked, Tiled allowed several pages to be viewed at the same time, but each pane was separate and could be scrolled or navigated independently. Linked was specifically for side-by-side comparisons and scrolled both panes together. You're asking for something more like Linked tabs - some people just want to more efficiently use space on large monitors by showing multiple (potentially unrelated) pages at the same time.
Opera itself doesn't support importing a text file of links or pasting clipboard content consisting of multiple links (separated by newlines for example). There might be an extension that does it though.
I think pasting a line-separated or tab-separated list of links that's in the clipboard would be nice though. So, would being able to import a text file.
It's really a shit. Sorry.
Uninstalled Opera from my laptop incl. data, cleaned up registry, re-installed Opera, logged into my account.
=> No bookmarks will be taken / synced from my PC
=> Default bookmarks by the new Opera installation are synce to my PC - and exist now 2 times (e.g. "Travel").
How can I fix this syncing problem?
