Looks nice but it's more a kanban board rather than a Trello clone. I don't doubt you're that skilled to build something like this "before lunch", but in my experience it is highly unlikely.<p>A few tips:<p>- Add a landing page or at least a demo of how it looks<p>- Remove those paddings and go full screen<p>- Remove transitions, they may look good but they're not usable in this case<p>- App feels heavy, not sure because of transitions, but feels slow.<p>Also if by simple you mean this:<p>- REST API and API documentation<p>- Invites sent via e-mail<p>- Full design<p>- Twitter integration<p>- Users and Abilities<p>- Multi-teams feature and ability to switch<p>Then I don't know what's simple anymore.
