I just hopped to postmarketOS and I wanted to be like those crazy people that move Dolphin’s sidebar to the left. It litterally STRETCHES it. I can’t see my files now. I compared Dolphin vs. GNOME Files to show how good they are when in a size.
I don’t seem to be able to have 2 toolbar panels on the same side. When I drag one over to the other edge without a panel the area expands to indicate where the panel will pin once I drop it but if a panel is already there it doesn’t do that. I can however get it to drop above or below the existing panel.
To achieve this, unlock the panels (right click on Places label), then with the dolphin window not maximized, you can drag and drop the panel to the right.
