I think it would enhance the game to add the ability for certain windows to be used as exits from structures. Yes, Ideally on the first floor. Rationale: So if I'm stuck in a house surrounded by zombies, a secondary window exit would probably be something I would do if it would give me a chance to escape. There are certainly plenty of windows that are large enough to escape from as well already in the game. It could be somewhat similar to the fence stepping animation, but of course for a window. Also, there could be risk of a minor bleed due to glass cutting you. This would add to the realism, open up more tactical and escape options, and hopefully wouldn't be a huge chore to add to the game.
