Like many people, I allocate effort to tasks in terms of hours or days. Keeping this simple, if I want to simply work in days, then 'percentages' of available effort form a given resource is practically useless - I have no simple way of converting percentages to days.

If, for example, I want to allocate 3 days from one person, and 2 days from another to the same task, then Omniplan does not seem to offer a way to do this. However, this is a *very* common requirement for me - and, I suspect, many users.
