but the screenshot is a bit misleading because it is a very low screen resolution (just for demonstration purposes)
with tasks from the same application being grouped i would have to have about 10 different applications open before that happens
if you need i guess you could use a separate horizontal panel only for the task manger, like i did in this screenshot: https://cdn.pling.com/img/f/f/7/7/7a74d8fde8b0c8ab6c80827cdf66b3a48fbf.png - Jan 03 2021

abstract mac-like buttons dont't go well with aero-glass-like frame. also, the button alignment seems off. - Jan 05 2019

you have to configure the panel a bit (task manager icons only, do not rotate buttons, clock show date below time, date format, sysmon height, etc) for everything to look right - Dec 12 2018

I made a plasma theme with color scheme support before, not with gradients though.
For me, there's two more issues with it:
First, titlebar color is not supported, only "Colorscheme-Highlight" (i.e. selection background) color. But the selection foreground color will not be used for the titlebar text.
Second, and more importantly: i need (dark) border and (bright) highlight shades for 3d effects. I use a simple shading algorithm (taken from QtCurve) for that. I would have to do that with semitranslucent black and white layers, but depending on the brightness of the background, some colors would always look bad. - Sep 11 2018

As a matter of fact, i am working on a matching aurorae decoration right now. Aurorae is a bit limited, but i'm trying to come up with something. - Apr 13 2017

2) go to System Settings > Application Appearance > Style, choose 'QtCurve' as Widget style, then 'Configure...', then, in the QtCurve Configuration, choose 'Import...' and add the style
3) go to System Settings > Workspace Appearance > Window Decorations, choose 'QtCurve' there as well - Apr 07 2016
