I´m using Vivaldi for two years now on different devices and there is only one thing I miss: The send-tab-function. I want to have the possibility to send tabs to other devices. It´s a nice-to-have feature that it works the other way round but I don´t want to click a link on 5 different devices to get this webpage on my device. Right click -> Send tab to -> device 1, 2, 3, whatever ... It could be so easy, I guess.
