How do I minimize the UI Builder window?

It’s not possible to minimize UI Builder window in Unity 6000.0.21f1

This was an intentional change in U6. It’s not specific to the UI Builder. All windows on Windows are no longer minimizable. I will add this to the feedback that we’ve been giving internally as well and we’ll see how we can continue to evolve our windowing system going forward.

Hello! @uDamian is mostly correct. This was an intentional change, but the good news is that there is an option to allow all these windows to minimize. :slightly_smiling_face: Go to Editor Preferences and select “Show All Windows in Taskbar” (You will have to restart the Editor)

When that box is checked, the minimize button will be enabled:

Longer explanation:

In 2022 LTS and earlier, secondary windows like UI builder could not minimize. For Unity 6, we wanted to add the ability to minimize windows. When we did that, these secondary windows started showing up in the Windows task bar and users complained that there were too many task bar items and it was confusing if there was more than one project open. It’s a limitation of MS Windows that you can’t minimize a window unless it shows up in the task bar.

I didn’t know about this option. It works now. Thanks for help!
