And also it was just working 4 days ago but then when I closed it and had to open it back it wouldn't open at all I have tried every YouTube video on how to fix it but it just wouldn't work.
In fact I just found out you can add any URL by enabling this flag: opera://flags/#sidebar-site-panel
Just enter this url, enable the flag and restart. Then you'll be able to see Custom site panels inside Sidebar setup
@leocg Yes but i need to see it when i use the tab button. So if you use tab on chrome you will see the preview as well. But i was wondering if that's possible on Opera as well
