Why is this still a thing? So many silly things like this make me just keep using firefox because Opera is half cooked. Firefox has the top left corner totally free for dragging meanwhile everything between the two icons in top left cannot be used, yet all the empty spaces below can. Why is it coded like this?
Plus we can't disable the Aria button from the "Sidebar setup" but you can right click to hide it? I could start listing all these annoying things missing settings too but they never change.
For now I have just disabled the entire sidebar, because at least that makes a draggable space above the unremovable menu button. I'll never understand products being user unfriendly and just saying "too bad".
