I would like to suggest the implementation of a 'Simplified Time Entry Mode'. In this mode, users would have the option to enter only the duration of a task, such as '2.5 hours for Task XY', without specifying the exact start and end times. This feature would streamline the time tracking process for tasks where precise time stamps are unnecessary.
This mode could potentially be a toggleable option, allowing users to switch between the traditional detailed time entry and the simplified mode as per their needs.
I believe this addition would not only enhance the flexibility of the app but also cater to a broader audience who may require a more straightforward approach to time tracking.
