works for me, it focus the next window to the left which is in my case firefox or alacritty or another dolphin. maybe update to 0.16

I found that it has nothing to do with Dolphin, but the "Horizontal gaps between windows" setting. If I set it to be larger than the "Left margin", e.g., 20px, then when I increase column width to the max with Meta-Ctrl-+, other windows would be completely out of the screen. In the case, closing the current window won't focus the previous one.
