During today’s Eco Lifestyle stream, gurus confirmed that the “free placement” feature that already exists in game for many objects, will now work with windows and doors. Currently the game allows you to press ATL on your keyboard and drag objects around, but doesn’t allow the same function with doors and windows. On June 2nd, that all changes.
Lastly, if you were wondering whether or not windows will stack, SimGuruGeorge confirmed on Twitter that they will not.
Windows will not stack. They still take up space per panel.
Note, that if you 'nudge' your single tile windows over onto two tiles, it will take up both of those tiles.
