When entering time from the timesheet view, ideally we would be able to select a project. Selecting the project would filter the task list to only the relevant tasks for the project/folder selected. We have quite a few tasks that we work on per project and sometimes remembering the name is not as easy. Having a filtered list will allow us to see the open tasks for the project and select the appropriate one.
We also quite often have multiple projects with the same task names and selecting the correct task when entering time sheets isn't always obvious. Selecting the project first then generating a filtered task list will be extremely useful for this use case.
