There are some features in my app which have high frequency of usage and the task involving those features are expected to be completed very fast. These features involve kind of serial data entry tasks and time to complete these transactions is expected to get lesser with increasing usage. I want to avoid using a datepicker as user will have to stop the flow of his fingers on keyboard and pickup the mouse to select the date.
At the same time I also want to give date-picker for other set of features which are not as frequently used such as generating report for a selected range of dates, etc.
How to ensure consistency in the app while avoiding datepicker for few features?
