Hi, I am new to KDE and don't know much about the code. Thanks to the code maps and nice namings in the repositories themselves, I found two directories (https://invent.kde.org/plasma/kwin/-/tree/master/src/effects/overview and https://invent.kde.org/plasma/plasma-desktop/-/tree/master/desktoppackage/contents/views) that look like the overview code and design but could not find the logic for the arrangement of the windows in the overview mode.
All the help is greatly appreciated.
