This is a long-standing issue that has been identified in the original newm WM. There is a need for improved support regarding the placement of panels and how windows should interact with them during resizing.

Regarding the panel appearing issue, the current behavior is that every time a panel is opened, it appears on the far right of the tiling system. This can be inconvenient if you want the panel to automatically appear on the far left. My recommendation is to modify this behavior so that panels appear on the closest edge relative to their position. For example, if you have panels on the left side of the screen, a new panel should not open on the far right; instead, it should open in proximity to the focused panels, such as on the left side.

The second issue is related to resizing, which is likely influenced by the properties of the tiling system. Currently, when resizing windows, they tend to overlap each other. It would be better if the windows could push each other instead of overlapping. This would provide a smoother resizing experience and prevent the need for manual adjustment after resizing.
