Only modern Ui trend I've enjoyed is dark mode, I remember using WindowBlinds back on Win7 to make my own dark mode but it still keeping the Aero look.
KDE with Volatile + Avalon icons have been the closest I've gotten to the look I really want on modern systems.
It probably would for me too, if it didn't become my default DE.
...it's weird to think about it. When that trainwreck of the initial KDE 4 release kicked off, I switched to GNOME 2, so I didn't give Trinity a chance; but when the trainwreck of GNOME 3.0 kicked off, I simply couldn't be arsed - instead I kept using it as MATE.
