@dzittin Good point, count me in. A trifle, but necessary at times. The more so it'd be attached to Opera improvements focusing on pseudo tile management I asked for in my previous requests:
Why you need to synchronize two windows and how?
Workspaces - synchronize windows' slides
Workspaces - desynchronize show/hide options
Workspaces - desynchronize icons
Vertical lines in Sidebar windows are not movable
Bookmarks page has hidden movable border line
Some vertical division lines on setting pages are not movable
Sidebar opening/closing windows is inconsistent
Sidebar - total mishmash
Up the ante of Opera effectiveness
Open thumbnails too in directory with images
Opera does not play playlists (*.pls)
