• Improved download dialog button accelerator keys to not require Shift or even Alt. Now you can easily choose to, for example, Open a downloaded file by just pressing O, or you can use Alt+O if you want, but you no longer need to press Alt+Shift+O. Similarly, you can immediately Save with S (or Enter or Space, which Vivaldi always allowed), and you can Save As with A.
• Further reduced Open button enablement to be immediate, instead of just reducing it from 1 to 0.25 seconds.
