Yes I've submitted countless numbers of feature request for this months ago. My qualm here is the fact that one can't set a notification for start, rather there is one for Due. As to how people use it that way, I don't know. I'd much rather be informed of when my task is to start than when it's due. If anyone feels the same way can they please send a feature request to Omni for this. The more requests we have the faster this feature can get implemented. Seems to be one of the few aspects stopping Omnifocus from perfection for me.
