The habit editor used to have three overlapping frequency controls (frequency, schedule, period) that didn't always mean what they looked like.

Now there's one clean schedule control that does the job. A real time picker (when the habit starts, how long it takes) replaces the old time-of-day dropdown. And a "type the number when you do it" mode for numeric habits (push-ups, glasses of water, pages read), so you can log "50" on a busy day and "0" on an honest one.
