Thank you for your information.

I started experimenting with some more custom images and i now noticed the Auto Color one (which is the one i actually prefer) works with a better scale as well!

Although i noticed that the image size did not cover the entire height of the taskbar (you can see this when the button is hot / hovered over).
Any idea if this is easy to change?

I also notice the blue logo is gone now when i press the button. Wasn't this 'auto color' button supposed to keep that? (Or am i confusing this with yet another start button)?

[Edit]
What i am actually saying is... would it be possible to just change the size of the default button? (The one that turns blue when you click it?). I just like the way it looks and animates.

(See attachment: taskbar3 to see which one i mean

).
