No visual effects on toolbar buttons (Opera 18)?
In Opera 18 there is no hover/mouse over effect on the toolbar buttons. When I move the cursor over a button or click one there is no visual feedback. Is this really by design?
This is by design. Look around on your Mac. This is the OS’ feel.
Fair enough, but that's only valid for the hover effect. Opera's buttons don't change even in their pressed state, which buttons do in e.g. Finder or Safari.
Furthermore I think the reason I find the lack of hover effect jarring in Opera is that its buttons don't really look like buttons in other OS X apps, those are usually outlined and look like well... buttons.
