Icaros Desktop is a pre-configured AROS desktop environment for the PC platform, distributed on a bootable live media. The AROS Research Operating System is a open source lightweight, efficient and flexible desktop operating system, aiming at being compatible with AmigaOS 3.1 at the API level, while improving on it in many areas.

If you have installed patch 03 (or 02 and then 03) on Icaros Desktop 1.3.3, you'd may be surprised to see that nothing has changed - at least in the user interface - in drawers and windows. The fact is that window can be iconified, but there's nothing to do that on title bars. So how can you iconify a window? The answer is that a button exists, but you have to enable it by yourself: just go to the Prefs drawer and run the Zune preferences program. Select the Windows option in the left menu and check for the Control section. You will notice four buttons called M, S, P and I. Click on the I button as shown in the image below. Click Save and reboot. From now on, you will be able to iconify (almost) all your windows.
