Timeline

The Timeline is a Gantt-style view that displays your Time Flow Tasks as horizontal bars on a calendar grid. Switch to it by clicking Timeline in the toolbar. Tasks can be dragged, resized, and scheduled directly on the grid.

Layout

The Timeline is split into two areas:

Task Board — a collapsible sidebar on the left showing your Tasks as cards.
Gantt grid — the main calendar area where Task bars, milestones, and dependency arrows are drawn.

Click the chevron button between the two areas to collapse or expand the Task Board.

The Task Board lists Tasks in two collapsible sections:

Unscheduled — Tasks that do not yet have a start and end date on the grid. Drag a card from this section onto the grid to schedule it.
Scheduled — Tasks that already have dates. Click a card to scroll the grid to that Task.

Each section has a category filter dropdown and a title search field at the top to help locate Tasks quickly.

The Grid

The grid header shows month markers across the top and individual day columns below. Each column shows the day of the week and the date number. The first day of each month is displayed in bold.

Today's column is highlighted with a subtle colour overlay so you can orient yourself quickly. When the page loads, the grid automatically scrolls to today's date (or to a specific date if you arrive from a link).

When the organization setting Exclude Weekends from Durations is enabled, weekend columns are removed from the grid entirely. Boundary stripes indicate where weekends would fall.

You can pan the grid by clicking and dragging on an empty area.

Task Bars

Each scheduled Task appears as a coloured bar on the grid. The bar colour matches the Task's Category. The bar displays:

The Task reference and title.
The category name.
A time chip showing logged hours — with colour coding when the Task approaches or exceeds its estimate (orange at 80 percent, red at 125 percent).
A duration label (e.g. 5d) at the far right.
State icons on the right: a lock-clock for in-progress Tasks, a lock-check for completed Tasks, an archive-lock for archived Tasks, and a plain lock for manually locked Tasks.
An Epic reference prefix in the Epic's colour, when the Task belongs to an Epic.
A red border when the Task is blocked.

Click the three-dot on a bar to open the Task edit dialog. Click the magnifying glass to open the inspect (read-only) view.

Ghost Bars

When Ghost Bars are enabled in the Timeline configuration, a semi-transparent dashed bar appears behind the actual bar. This ghost represents the original projected schedule (plan). When reality drifts from the plan, the gap between the ghost and the solid bar makes the variance visible at a glance.

Backlog Bars

Backlog Tasks that have time entries logged against them appear on the grid as a special bar style — transparent with a dashed outline. They are not draggable or resizable. Their position is derived from the dates of their time entries.

Milestones

Milestones appear as coloured vertical lines spanning the full height of the grid, with a diamond marker at the top. Click any date cell in the header to create a new milestone on that date.

When a milestone has a Cycle Start Date, a shaded band stretches from the cycle start to the milestone date, visualizing the cycle period. The cycle can be resized by dragging the left edge of the milestone bar.

Click a milestone's diamond marker to open its edit dialog, where you can change the title, colour, date, cycle, and other properties. For a full overview, see the Milestones and Cycles page.

Dependency Arrows

When Tasks have parent-child dependencies, curved arrows are drawn from the parent bar to the child bar. The arrow colour matches the parent Task's category colour. See the Dependencies and Chains page for details on creating and managing dependencies.

Overhead Bar

When enabled, the Overhead Bar sits just below the grid header. It shows a vertical bar chart for each day where time has been logged. The bars represent the proportion of general (non-targeted) time versus targeted Time Flow Task time on that day.

A day with 100 percent targeted time shows no bar segments.
As general time increases, more segments light up — green for low overhead, yellow and orange for moderate, red for high.
Hover over a day to see the exact split: targeted hours, general hours, and an overall effectiveness percentage.
Click a day to open the breakdown dialog.

The Overhead Bar is a quick visual check on where your time is going each day. A persistently high bar suggests that a high percentage of time is being spent on non-Task work. The Work, Overhead and Flow guide discusses strategies for keeping Overhead visible and under control.

Epic Bands

Epic Bands are semi-transparent coloured bands that group Tasks by Epic on the grid. When enabled, each Epic's Tasks are visually enclosed in a band matching the Epic's colour. This gives a high-level picture of which Epics occupy which time ranges. The opacity of the bands is adjustable in the Timeflow settings .

Scheduling and Moving Tasks

There are several ways to place and adjust Tasks on the Timeline:

Drag from the Task Board — drag an unscheduled card from the sidebar onto the grid to set its start date. If the Task already has time entries, it will snap to the actual start date instead.
Drag a bar — move a bar left or right to change its date range (subject to lock rules ... see below).
Resize edges — drag the left or right edge of a bar to extend or shorten it (subject to lock rules).

Lock States

How much you can move or resize a bar depends on its lock state:

Done — fully locked. The bar cannot be moved or resized.
Doing (in progress) — the left edge is locked (you cannot move the start date backwards) but you can extend the right edge to push the end date forward.
Manually locked — fully locked via the lock toggle on the Task. No movement or resizing is allowed until unlocked.
Default (unlocked) — fully unlocked. The bar can be moved and resized freely from both edges.

Dependency and Milestone Warnings

When you move or resize a Task that has child dependencies or is near a milestone with dependency conflict detection enabled, a confirmation dialog may appear. It lists the affected Tasks and any milestones that would be violated by the change, and asks whether to proceed.

Timeline Configuration

Click the gear at the far right of the filter bar to open the Timeline settings. The following options are available:

Task Board — show or hide the left sidebar.
Ghost Bars — show or hide projected schedule bars behind the actual bars.
Overhead Bar — show or hide the overhead visualization below the header.
Chain Bands — show or hide Epic grouping bands.
Chain Band Opacity — a slider (1 to 5) controlling how opaque the chain bands appear.
Timeline Offset — a slider (0 to 4 months) controlling how far before the earliest Task the grid begins. Useful for seeing upcoming availability.
Hide Milestones — toggle to hide all milestone markers and cycle bands from the grid.
