All Buttons have the same color

I find it very annoying that all buttons have the same color. For example, in the post editor, the “Save” / “Update” buttons have the same color and weight as the “Move to trash” button. I have not found a way to change this. WordPress does know differently styled buttons. This should be added urgently. Or is it possible with the Pro version?
I also miss the possibility to add more separators in the menu editor.

And thank you for this basically really nice plugin!
