I have never used this forum, but as a lifelong user of this site, why do you feel the need to over-do a simple thing such as a UI??? Compared to the previous, this UI feel barebone, empty, unfinished, and simply uninspiring. I mean not like the old UI did anything revolutionary either but this is like 1 step forward, 4 steps back. There's an old saying, "If it ain't broke, don't fix it."
Many have already said this, but please just give us an option like a legacy mode to revert back to the old UI. Curseforge has this, Gamebanana has this, why can't we have this too?
