@dfonseca1 Vivaldi copied it, in a certain way, from Opera Presto. if Opera didn't reimplemented it until now, most probably it's because the feature doesn't have that many supports to worth the efforts.

@leocg
Thank you for your reply leocg,
I didn't know it was related to the difference between desktop and web versions of Spotify since I haven't actually explored the web counterpart ever before. Then, I will contact Spotify for this feature.

Thanks!

Oh many people need this feature which may have requested long time ago. Synchronization of extensions is one of most important reason I use Chrome. The day Opera supports sync extensions, the day I will come back.
Hope a better Opera.

Hello,
I use Opera GX and it also doesn't show notifications. Even enabling them.
Please developers, allow this.

@phoenlix I believe workspace feature and my flow are both still can be develop to something more. maybe they opera developers make them work together or something. I don't know. but for now both features are really cool but they are very unfinished in terms of functionality. I would also like to see some auto-tab-hibernation feature...
