Note: Not sure if recommendations for opera GX can be posted here but I found nothing else. (this is my first time here)
The recommendation is simple, the task island provided in Opera should also be in Opera GX. The reason I think this should be implemented is because many people may enjoy the features in opera GX (for example GX control) and may also like the task island feature in opera.
The reason I want it to be implemented in opera GX is because I find myself using Opera GX more because of the GX control and a few other reasons. I really like the task island feature in original opera and I wanted it in opera GX.
