The answer is to drag the tab from main window to your 2nd window on 2nd monitor, but the trick is to hold click and hover it above the + symbol on the other screen window for up to 2 seconds, you will then see the tab underneath move which means u can let go of left click now to drop it. Repeated test heaps of times, it works. nothing else works however

@leocg I want a time widget, because when i use oled main monitor and have Windows 11 auto hide taskbar, windows autohides taskbar on both monitors, meaning i can no longer see my time on my 2nd monitor, however if there was a widget of time in opera gx i could add that below the weather and see the time instead of not being able to see the time without alt tabbing out of a game to mouse over the taskbar to see the time. I always have opera blank screen up on 2nd screen.
