Left, resting: one line, "Follow-up in 2 days" + four channel icons. No word-list.
Right, on Edit: a timeline. Channels are icon toggles (Email · LinkedIn · iMessage · Call), not pills. Each step is one quiet line with your real reply rate; selecting one opens its editor.
Nothing lost: per-step language, channel, day, the Call task, and the 90-day data are all here, just calm. iMessage stays.
