Sorry if this wasn't clear. The window manager can display multiple
windows (our frames) tiled into some sort of grid, in which case
everything behaves correctly, or it can allow one of the windows to take
up the full workspace, and other windows are only visible as a sort of
window title bar, either tabbed along the top, or stacked along the top.
I'm attaching a screenshot, that's stacked.

My understanding is that this is *not* equivalent to X11's
iconification or minification, where the window disappears and shows up
as a icon in some notification area. i3 does have a notification bar,
but I wouldn't know how to send a window there. In the screenshotted
situation, i3 provides keybindings for switching focus between the
stacked windows, but I believe in X11 terms, all three windows are meant
to be visible, you're just switching which one is "foremost".

I've got i3 set up to use stacking by default, meaning that as new
windows are created they are added to the stack and displayed on top.
You can also have them tabbed or split by default.

I hope that makes sense. I'd be happy to try to contact an i3 person and
ask them exactly what's happening, in X11 terms.

Thanks,
Eric
