If someone is using automatic vacation, it would be useful if the time left column on the main page included the number of vacation days they have left.
For example this game between me and MJL is currently showing me that my opponent has less than an hour left to make his move, however his profile shows that he actually has 29 automatic vacation days, so he has 29 days left before he times out, not less than a day, so it should show that on the main page.
