Snap document window to artboard size
In Photoshop, when you have a document open you can drag the window bigger/smaller, revealing the 'canvas' around your document.
If you then use 'CMD -' or 'CMD +' to zoom in or out of the document, the actual document window snaps back to the size of your PSD.
Illustrator acts differently - if you zoom in or out, the document window itself remains the same size - you just see more of less of the document's canvas around your artboard. It's a pain, as if you have several documents open that you want to be able to see at the same time, you have to individually re-size the document windows of each so they fit on screen at once.
I can select 'View > Fit artboard in window' (or CMD + 0) but that doesn't resize the window - it just resizes the artboard to fit... it still leaves the window as wide/tall as it was. I guess I want to do the opposite.
What I'm after is a way to 'fit' the document window to the size of the artboard.
