Since Opera's design does not really account for the possibility of vertical tabs, many of us use separate extensions for this purpose. The biggest issue with this is that Opera does not support the tabGroups API, so it's not possible to name specific groups/tab islands in the extensions either. I would like to suggest that even if Opera itself does not plan to support naming groups, it could still provide the option for extensions to utilize the API.
