Improve Time and Duration UX & UI

As it stands, you have to scroll to set a time and duration for your tasks, unless you’re using a preset for duration. I find this method slow, cumbersome and prone to errors. I would really like a more direct way to input time and duration. I want to just type in the start time and type in how long it will take to do a task.

Also, it would be excellent to have more duration presets.

I was debating using Prosper over Structured. I ended up not doing that, but this complaint is what Prosper got down right. I was really considering just for this feature alone.
