@avl Thank you for the reply. What you suggested does reopen a tab without overwriting the currently selected tab. Yay!
It seems, though, that the tab menu doesn't group the closed tabs. It looks like one huge, disorganized list to me.
As per the Google example, one closed browser window had 23 tabs, another had 21, and another 9. They are so neatly organized, I am happyface! I have the option to restore each of those groups in a new window as per the listed groupings. I am happyface x2!
Does Opera have a similar feature? (Please oh please oh please be yes. >.>)
I did discover that I can use Speed Dial to save tab sessions in a manner similar to the Session Buddy web extension. Yay!
My others tabs issue is that I can't seem to figure out how to set a warning when I am closing a window with multiple tabs. I somehow accidentally did that once and was sadface because everything was gone.
So, like, really, I am a tabs fiend. Ahem.
Thank you @kmielczarczyk for reaching out, it is greatly appreciated.
By any chance would the Opera team consider to bring back this function - that was really useful btw - so we can have a more enjoyable customization of Opera ?
