Sizes in every list
Folder sizes appear beside files, in every folder you open. Sort by size to find the big ones first. Sizes are remembered, so big folders are not measured again each time.

Disk Usage (⌥⌘U) draws any folder as a picture where area is size, so the big things are the big blocks. Click a block to look inside.
