ATTENTION PLASMA WIDGET, THEME AND ADD-ON DEVELOPERS:
KDE loves all your stuff, but you need to port it for it to work in #Plasma6. We have created a handy, easy-to-follow guide for extensions and widgets at
https://develop.kde.org/docs/plasma/widget/porting_kf6/
Theme developers, please check out this:
https://develop.kde.org/docs/plasma/theme/theme-porting-to-plasma6/
Porting is quite straightforward and should not take you long.
Keep your users happy! Port your stuff!
Looks good (the extension). Any other good tiling extensions with keyboard and GUI support? I would like to explore a few to see which one works well for me
