I love being able to see the history every time I open up a tab, that way it reminds me of exactly when and where my teammates and I are on a project.

I like Group Office because of the wide variety of functions in terms of project management. Its calendar tool allows me to schedule meetings that I can have in a period of time, I can also schedule activities or tasks. Personally, I also like its function to see the modified files in recent days, so I always have the latest projects I work on first.
