&gt; Ideally it would be nice to enhance all window managers and somehow make this possible in a different way. You&#x27;d still have practical problems in that the theme of the window manager won&#x27;t align with your toolkit though.<p>&gt; But I prefer actual progress instead of the theoretical ideal solution that&#x27;s way more work and involves co-operation with everyone.<p>You know what? Let&#x27;s start by not making these silly thick titlebars, and not making these silly assumptions that everyone uses the library &#x2F; framework of the day. Because <i>these</i> are actually idealistic and will never work out in practice.<p>GTK hasn&#x27;t learned from the Windows 95 style GUIs (don&#x27;t know any names) which never had any space problems in the first place. But I think it has a lot to do with portability to netbooks &#x2F; tablets &#x2F; smartphones in that they drove this development (look at Windows 8).
