New 2025 UI redesign is absolutely atrocious

Title. The server list was made way too small, the server icons are square now (which I hate), the user indicator in the bottom left corner was given way too much space, there's way too much spacing in the member list, there's a new "Activity" dropdown *INSIDE* the member list which I cannot hide whatsoever, and the sizes of the buttons themselves (i.e. gifs, emojis, inbox) are too small. Give me a way to switch back from this garbage.

Actually, calling it “garbage” is too nice, but I don't know what else to call it.
