Hello

I've created two opera accounts in order to manage separately, bookmarks for my needs, my environnments, configuration, etc..
As an exemple :
Account1 is dedicated to my hoobies
Account2 is for my financials topics
Each account have dedicated bookmarks according to the topics they are concerned with.
My issue is that opera merges, synchronizes all bookmarks, for all my accounts.
Bookmarks don't seem to be managed separately.
I don't want account1 bookmarks to be merged with other accounts bookmarks.
How can i avoid this ?
Thanks
Regards
