Describe the bug
When moving a window from left to right using the komorebic move right command between 2 monitors, the moved window is added to the right side of the 2nd monitor instead of the left.

This issue happens when the 2nd monitor is using the UltrawideVerticalStack layout. I also tested in 'BSP' and the window is added correctly. To the left, instead of the right.

To Reproduce
Steps to reproduce the behavior:

Dual monitor setup

Have at least the 2nd monitors use the UltrawideVerticalStack layout
Open a window on both monitors
Move the window from the 1st monitor to the 2nd monitor using the komorebic move right command
See bug

Expected behavior
The window coming from the 1st monitor is added to the left side of the 2nd monitor.

The insertion position when moving across monitors depends on the last focused container index on the target monitor, and the case of UltrawideVerticalStack layout is a little more complex as the container at the index 0 occupies the largest position (in the middle) rather than the leftmost or topmost position (which is usually the largest position in other layouts)

Ah I see that is why when there are 2 windows on the 2nd monitor, a window on the 1st monitor will be placed in the middle of the workspace when moved with commands.

So I would say, let's keep it simple as this feels like more of a feature than a bug 😄
