[Suggestion] Bookmark Sidebar left/right padding settings

[Perhaps-This]

Opera GX bookmark sidebar features empty space [forced padding] on
the left and right of bookmarks displayed. I'd like to see some added UI
settings to adjust that.

For reference, right side padding is approximately 2 cm of empty space on my 2k display, which is consuming a good chunk of horizontal screen real estate, which I'd prefer be used to display more of my bookmark's name/label.
