I do not give up on my openbox. I use it with LxQt. Now there is a Labwc, similar to openbox. It uses its XML spec for config and is similar. But I am still on

I do not give up on my openbox. I use it with LxQt. Now there is a Labwc, similar to openbox. It uses its XML spec for config and is similar. But I am still on X until all issues are resolved. Can I use openbox on KDE now? It used to be possible, I can choose WM in LxQt. Back then every WM had a --replace option.
