dalto you can never please everyone 🙂
reg the blur, I'd love to have it the same blur but that's not possible as far as I can see (unless there is sone voodoo magic which can be done) as it works right now, first the black area gets rendered via panel-background and on top of this gets the plasmaoidheader added, so this causes the issue with the lack of blur.
I have to be careful with the opacity level because it suddenly turns into a diff color because the dark area behind it starts coming through etc.
