With the new OSWindows you can create multiple native windows. But... this is cool to allow people to do their stuff, but it does not match very well with the development philosophy of Pharo, where we open many windows at the same time. Imagine 20+ browsers, inspectors, playgrounds opened, all mixed with your regular browsers, mail, any kind of applications and you will understand why we prefer to keep the MDI. Said that... we actually want to support SDI also for development (optional for users), but this is a lot of work and will take a lot of effort. But we'll arrive there, with time (and help).

If a window manager does not support dealing with multitudes of applications with multiple windows, then the window manager does something wrong.

I simply hide these other applications - actually I use auto-hiding after some time period. No need for an MDI.

Let's look. My Mac now has 11 apps open: mail, calendar, contacts, browser, previewer, notes, two Lisp systems, several terminals, a finder, twitter, ...

Both Lisp systems use native windows, menus, buttons, dialogs, text fields, ... each Lisp editor is a separate window, ...

Multiple (native) windows + tabbed browsing is IMO better than a single-window MDI. Remember Linux and other Unix desktops already support multiple virtual desktops to manage many windows; you shouldn't try to reinvent this in Pharo.
