Whenever it comes to a discussion about the kde4 global shortcuts framework things heat up. Somehow people get really agitated if they learn how it works. Why? I don't know. It's a framework like any other. It has its ups, it has its downs. So lets have look where the problems are.
I switched to kde4 only 2 month ago. At the beginning i was unable to get the composite effects of kwin4 working with my nvidia graphics card. During that span i started to dislike one of oxygens decisions. I think i read somewhere it was a conscious decision. The following screenshort illustrates that feature. As you may notice there is no visual separation between the windows. The title bar has the same grey as the other windows background. The eyes have no help finding the title bar and that means no help in finding the menu. I hated that and switched to another window decoration.
I was about to do the same, but with Jos Poortvliet doing the work there is no need to do it twice. Head over to the Jos Poortvliet Blog for some screenshot of current plasma themes.
Tomorrow i hopefully will find time to write down some of the points i love and hate about the new kde version.
