Leantime/leantime — reverse-engineered prompt

Build me an open source project management web app for regular teams who don’t want something as complicated as Jira. It should feel simple and friendly, but still powerful enough to run real projects from goals through planning and execution.

I want users to be able to create projects, manage tasks with kanban, list, table, calendar and timeline views, add subtasks, dependencies, milestones, sprints, comments and files. Include a personal “my work” dashboard, project dashboards, reports, status updates, time tracking and timesheets.

Also add places for strategy and knowledge work, like goals and metrics, wikis or docs, idea boards, retrospectives, SWOT, risk analysis and a business model canvas. It should support teams with roles and project permissions, two factor login, multiple languages, and integrations like Slack, Mattermost or Discord.

Please keep accessibility and neurodivergent users in mind, especially ADHD, dyslexia and autism. Use PHP with a MySQL or MariaDB database, and make it installable on a normal web server or with Docker.
