The bottom of the composer used to stack three unrelated-looking piles: media buttons mixed in with scheduling actions, an unlabeled sets strip floating over a bare "Post to:" row, and four different button styles fighting over one action row — with the exact-time widgets wedging themselves between them whenever that mode was on. It's now one coherent bar: a dominant Schedule button on the left, the timing toggle beside it, exact-time controls appearing inline only when active, and everything secondary grouped quietly on the right.
