When I started to use Opera browser almost a year ago I remember using a short-cut to toggle (open and closed) the whatsapp panel. But after a serie of new releases it disappeared.
Now, I don't know if I dreamed about it or if that was the reality at the time, but that feature would be very helpful for people constantly typing on a keyboard barely using the mouse (like developers ^^).
So to wrap it up, I suggest adding a WhatsApp shortcut and maybe in the future the possibility to bind new shortcuts to any built-in extension/feature.
Hello, I find it quite interesting, because I have tried and I can not, I usually use the web version of WhatsApp (official), although I have been using GBWhatsApp for some time, and a shortcut of these would suit me very well. Greetings!
