I just sent Omni a feature request for the ability to flag contexts as well as items and projects. This would allow for the construction of a much more flexible perspective of the "due or flagged" variety. I would find it useful for contexts like "before trip" or "significant" (something that advances toward a long-term goal). The flag by itself does not convey much contextual information about why an item is flagged, after all. It's a small thing in many ways, but seems to offer rich possibilities and would allow me to create a single hotlist perspective. Thoughts, anyone?
