That is a possibility to add. There are a few spare columns that can be added to that display.
I had thought of lab completed but days remaining is a good suggestion.
Anything else people want shown - subject to the space available?
By no means are these super necessary as you should know this about your own alts but maybe people with a lot? Race of each is an option and so is maybe Clan. but i agree that time until deletion is by far the better/more important information. arguably i would consider lab completion important for when people need help on particular labs some one can check their alts at a glance to see if they have any one on that lab.
