https://appfire.com/ as an example, but I’m always flummoxed how ALL wordpress themes cap at 10 words per line of text in the body of the blogs, and 25cm of white blank on either side (10 inches).
I need a bigger screen.
I keep my terminal (read: text editor) fullscreen because then I have enough horizontal space to have two panes open next to each other (sometimes with an additional directory viewer to the left).
99% of the time, I'm in the terminal or the web browser. I don't understand what I would gain from not maximizing them, but I do understand what I would lose.
If you're visually impaired, you'll also likely find yourself needing to maximize because all of the blank space used in modern design trends means that if you scale up the app or the font sizes, all that empty space the app is burning up forces you to maximize the window just to fit the important elements on the screen.
Completely the opposite. It's the influence of having computers powerful enough to have massive multitasking. Arranging windows like papers on a desk is easy when you have a handful of simple programs and a couple of browser windows - it's very different when you have 100 tabs with their own task-swapping logic in front of 20 other programs. You've already lost easy swapping so you might as well gain the extra pixels.
For example, Photoshop, your photo document was contained in a window, your tool palettes were windows, etc. If you were viewing a reference image, you could have that open in a separate window alongside the image you were working on, rather than having to switch tabs or switch windows.
Today, we all have gigantic monitors, many have more than one, but for whatever reason people want to maximize or tile windows. Maybe it's the influence of the fullscreen only, unitasking paradigm from phones and tablet computers, but it just doesn't make much sense to me on a desktop computer.
