Before version 25.02, I was able to scroll through open windows while dragging a window or a file using my scrolling keybindings:

Mod+WheelScrollUp   cooldown-ms=150 { focus-column-left; }
Mod+WheelScrollDown cooldown-ms=150 { focus-column-right; }

Mod+H           { focus-column-or-monitor-left; }
Mod+L           { focus-column-or-monitor-right; }
Mod+Left        { focus-column-or-monitor-left; }
Mod+Right       { focus-column-or-monitor-right; }

With these keybindings, movement across windows and columns remained consistent between normal window switching and repositioning via drag-and-drop. However, with the new gesture (which, by the way, is excellent UX design), the ability to move between columns and windows using keybindings has been removed, making the gesture the only way to reposition a window.

This new behavior also creates an issue with file dragging. If I drag a file and move the mouse to the monitor borders, all windows and columns scroll as expected. However, if I use a keybinding, the focus changes, but the visual scroll does not occur.

I truly appreciate the improvements in usability, but I was wondering if there is any way to restore the previous functionality alongside the new gesture. Thank you for your hard work and for continuously enhancing the user experience!

This is semi intended because what happened with DnD scroll is that the view is immediately frozen and keeps frozen over the duration of the drag. I'll need to think if there's some clean way to make the focus actions still work during this. Also related: #1174
