I - nearly - like it :)
In "oxygen-demo2.png" you show the UI controls. It looks good, but a
bit too flat for my taste. Could you do very subtle small color

In dolphin, the blue border is so.. "in your face". Sure, there is
probably a need for that border to indicate the part of dolphin that
has focus, but does the border have to be so bright shiny blue? A
white border with a small blue tint would be a nice experiment i

Nice job thus far! I don't care if you use QtCurve or something else.
As long as it looks good and is performant.
