Looking for User Stories and Opinions, on what features I should implement in my Project

Hi guys,

In college I got a task to create a Time Management Web Application. It's for the next 5 months that I will be developing it. I'm looking for opinions and recommendations for you guys.

My Questions are:

What features would you like to see in a Time Management Application for both normal users and students who are doing their projects/final thesis etc.

What unique features do you believe are lacking in most Time Management Applications/Websites and that you believe should be available?

What is the biggest disadvantage about most time management apps?
