Publishing to five networks used to be all or nothing to look at. If one failed you had to work out which.
Now hitting publish leaves a toast on screen with a row per account and a progress bar. A clean run disappears after a few seconds. Anything that failed or came back with a warning stays put until you deal with it.
Per row
A failed row gets a red marker, and hovering it tells you why it failed. Next to it are two buttons.
Retry republishes that one account. The rest are left alone.
Schedule takes that account out of the group and opens the composer on its own, with the schedule dialog already open. Useful when a network is having a bad day and you would rather try again this evening.
A row that is still going when the watch window ends is treated as a failure you can retry, so the toast never sits there spinning forever.
