kde update 4.9 & problems with auto-grouping windows

view full story

https://bbs.archlinux.org – Unfortunately, I am using Oxygen window decorations already.I do have the "Attach as tab to" option but it is a pain to have to group every window manually. I've discovered that auto-grouping does work for windows opened on the same virtual desktop but if I open a new okular window from konsole, say, I get a new window on that desktop rather than having it end up attached as a new tab to an existing window on another desktop. I can work around it by having all okular windows start on a standard desktop but this is a pain as I didn't want okular to behave this way.Thanks for (HowTos)
