Do a special context notifying when employee can leave
For some meticulous people who does not want to work more than an official working time it can be useful to notify when working day (read hours) is over. Saying you came at 10:47 and left for a lunch for an hour. At 19:47 (in 8 hours (9 - 1)) Orangutan should tell something like: “Hey! Your working day is over now! Please go away!”. Of course, this should be a “feature” which should be turned on to work. The same, perhaps, could be done for a lunch (e.g. “Hey! Go have a luch now!”).
