ORGANIZE YOUR WAY Structure work into boards and projects, each with custom columns. Switch between Kanban and list view at any time. Drag and drop tasks between columns, reorder them in a list, or collapse columns to reduce noise. TASKS THAT GO DEEPER Every issue supports sub-tasks with individual due dates and time estimates. Track progress with a built-in timer, set priorities from Urgent to Low, add color labels, write Markdown notes, and link related issues with blocks / blocked-by / relates-to relations.
