Todowing is a Chrome extension for Todoist users whose sub-tasks disappear in Today, Upcoming, Boards, Filters, and Labels views.

Inline nesting - sub-tasks appear under their parents with hierarchy intact, four levels deep
Full row detail - each sub-task carries its own due date, priority, and labels
Act in place - check off, rename, reorder, and add sub-tasks without opening the task
Focus sessions - pick tasks, estimate time, and run a countdown timer beside the list
Personal styling - seven color palettes, fifty fonts, text scaling, and Apple Calendar events in Today
Private by design - talks only to the official Todoist API with no analytics or tracking

It is useful for Todoist users, freelancers, and teams who plan with checklists and want their hierarchy visible everywhere.

Free tier covers nesting with 5 sub-task rows per task; a one-time Lifetime unlock of $19.99 removes all limits and includes every future upgrade.
