Every single time I'm on desktop and I see a GUI that sucks, I know it's mobile's fault. Why this button so big? Mobile. Why spacing? Mobile. Why this list of 6 clickable items with one line of text each takes up my whole screen's vertical space? Mobile. Why no more status bars and tooltips? Because you can't hover on mobile. Why is the filter of this table below the table instead of above the table's headers? Because the thumbs won't reach the top on mobile. Why the headerbar buttons have no labels? Because they wouldn't fit in the horizontal space in mobile.

I'm really not a fan of mobile. If possible, I'd rather ignore it completely and just let mobile users rotate their screens.
