A project tool that does not know what an hour costs.
Boards, lists, statuses, assignees. Everything about what is happening, and nothing about what it is worth.
A timer that does not know what you were working on.
A text box, a project dropdown, and a name you retyped slightly differently from the task it belongs to.
Project management with time tracking inside the task, so the hours you bill reconcile to the work you did.
