I love this app. But missing features for me would be shortcuts, to quickly do repeating tasks, for example, when opening the "create requirement", you could press the numpad in order to select the desired action.
Also ways to "code", or excel-type of expressions inside the app. For example, when using the point system, instead of entering a value in the point cost, you could put, for example, "=(point_value*3+1)/2", etc... Derived from this, a way to use if statements would be a plus. In conclusion, a section where you can enter code.
