What colours do crit, active and done use?

crit uses the theme's emphasis colour (red family), active is slightly darker than normal tasks and done is greyed out. Each of the four designed themes has its own Gantt palette.

How do two tracks run in parallel?

Tasks in different sections overlap whenever their dates overlap; no extra syntax is needed. Give the first marketing task an explicit date rather than after an engineering task.

Can I export to Excel?

No. Export formats are PNG, SVG, PDF, Word and PowerPoint. For a spreadsheet, copy the task list from the code.

Product Launch Plan Gantt Chart Template

Previewed in the “Cinnabar” theme; you can switch themes in the editor

When to use it

Release plans, launch stand-ups and cross-team schedules. The engineering track (regression, staged rollout) and the marketing track (assets, warm-up) run in parallel and meet at general availability; crit highlights the staged rollout in the emphasis colour.

Making it yours

Replace the marketing tasks with your actual activities: blog post, app store screenshots, customer email.
For several rollout stages write "Rollout 10%" and "Rollout 50%" as separate tasks chained with after.
Remove crit, if you do not want the highlight.
