I think it’s more of an evolution in the way we use computers than a problem. The original Office UI was made during a time of single monitor dominance and now dual monitors is the standard for companies.
My most-used applications for work at AutoCAD and Excel and it’s very rare I DON’T have them maximized. They both have ribbons but even if they didn’t, I can’t imagine using them in a small window. Really the only program I don’t run full screen is Notepad
I thought discord streaming was so dumb until I was trying to reach my friend something in a game. Now we use it a couple times per month, it’s great. I hate that I like Discord lol
