I'm not sure what is and isn't part of this theme, does this theme include the Kicker you show in the screenshot? Cause it sure looks different on my computer. I'd like to have a kicker that small too.

Would you mind changing the color tone of the notes widget? The white text on the light colors green, white and yellow is very very hard to read. BTW: Is it intentional that the blue note has an outline? And the German translation for the theme comment would look better as "Elegantes und minimalistisches dunkles Thema" (small grammatical correction). Or maybe better "Design" instead of "Thema" because "Design" is used everywhere else in KDE SC as translation for "theme".

Interesting approach but IMHO not fully consistent. Personal taste. I don't like the grey panel with the black widgets. Maybe because I have a more or less big panel. Apart from that IMHO the visible part of the panel is too big when the panel has a certain height (icon size 64+). It would look better I guess if half the height would be transparent and not just roughly one fifth. When the taskmanager sits in the upper transparent panel the task buttons look very nice with just that blue shiny marker - but on mouseover the tasks become black bricks which looks not that good on a transparent panel :(.
