What's harder is to figure out how things *should* work as you point out:
o where should it start? should the timeline include past dates by default? when the user says so? should it *ever* include past dates? o where should it stop? The last explicit entry is one possibility, user-input is another (but this would require changes to the user interface), a time limit specified by the user in some configuration variable is a third. The more one looks at these things, the more one marvels at the choices that Carsten and Bastien and Nicolas and the Babel developers (and on and on) have made: getting things so that they work *just* right most of the time and providing enough flexibility to cover most of the remaining cases is hard work.
