One relatively simple feature that is missing from RB is project budgets.
Redbooth allows us to log time on tasks and now the Gantt shows project timelines, a fundamental missing is the ability to enter a project-wide budget of hours/minutes (e.g 100h) so as time is posted on the project, there is a visible burn-down chart of the budget remaining.
As an MVP we don't need staff cost-rates, profits, money, quotes, material costs or invoicing, we just need a simple visual in each project of hours available vs hours spent. Of course this could become more sophisticated overtime but as a basic MVP this would be a killer feature that would keep us on Redbooth.
