This is more of a suggestion than a feature but I've had some serious lag only within the messenger and whatsapp side windows. The lag is new (and my rly good gaming pc isn't causing it). It has been happening since one of the updates im assuming and is obviously not pleasant.
Problems like these should obviously be fixed because Side Windows are like one of the 2 main reasons I use Opera instead of Chrome, and im sure im not the only one who chose opera over chrome because of the feature set. If you need to scare some investor that is what you should mention, i just want my smooth experience back. (The other reason i use Opera is because of the pop out window feature)
Thank you for coming to my ted talk
