Modification of the original Dyne theme by Lyrae. The minimise/maximise/close buttons on the top right appear when hoovered over with the mouse button. Sub-menu panels of the root menu are floating, sub-menu entries have an arrow behind them. Hope you enjoy it and of course props to Lyrae for the original :).
