Hello, I would like to share my feedback regarding the new OCA interface. As a presales engineer, my primary task is to build and optimize configurations. However, with the latest update, the header is taking up a very large portion of the screen — in some cases up to one third or more of the available workspace. This significantly impacts productivity, especially when working on smaller screens such as laptops. The reduced working area makes it more difficult to efficiently navigate and configure systems. Would it be possible to provide an option to minimize or collapse the top header more effectively, in order to allow a full-screen workspace dedicated to configuration? Having a more compact or adjustable header would greatly improve usability and day-to-day efficiency for presales teams. Thank you in advance for your consideration. Best regards,
