It would be really useful to be able to filter items based on their creation or modification dates, e.g., “show me all the items I added to this Project after January 1st” or “show me everything in this document that was changed in November”. I’d suggest the following:
- created: (including “today”)
- modified: (including “today”)
Anything else? If that’s too many, I guess you could use combinations of created-after and created-before to achieve the other two. I don’t mind if it’s an advanced-only (paid) feature.
