Groups: Extend filter constraints (e.g. time constraints)

[systemoperator]

Zotero allows defining really powerful filters. I created e.g. one called "recently added", which covers the last 7 days. (The numeric value can be set freely. Possible time units are days, months, years. Several filter constraints can be defined at once.)

Match all or match any.

It would be great, if JabRef could filter e.g. by different time units (filter using e.g. last modifed, creation date)

[systemoperator]

Would still be relevant.
