Thanks, I'll send in the feature requests.

Another one:

Some tasks need to be executed during specific time periods, such as during business hours U.S. time. These limits are connected to the task, not the person resource, although obviously the person resource's available time needs to overlap the task time limits.

How would this limit be set? All I can think of is to have some sort of new resource type of "Schedule" or "Time Period" that could be attached to the task, and the scheduling would then be only done during the intersection of the person and schedule resources?

[Edit: It just occurred to me that this is similar to room reservations, so I'll see if there's anything there that will help.]
