As many people here I have been a die hard user of Opera 12, while using Vivaldi as secondary. But as the resent beta added support for plugins and with that the possibility to add the adBlock, I felt I am ready to move to Vivaldi as main browser and retire the good old Opera. But have been disappointed after findiong out, that Vivaldi doesn't import the tabs. You know I have dozens of tabs open, some grouped in several stacks. It would be pian to move them manually. So please, please make it possible to import the browsing session (at least for Opera 12). Shouldn't be that difficult and you make the migration to Vivaldi much easier for a pro/heavy user, which is your declared taget group. Or may be I missed something and there are still a way to import the tabs somehow?
