 | LR-LIB-RECENT-ADDED | Recently added | P1 | ✅ | `cmd:library.source` (`recentlyAdded`), `crates/engine/src/view.rs` (`RECENT_DAYS`) | photos imported in the 30 days up to the latest import, newest import first, grouped by import day |
 | LR-LIB-BYDATE | Browse by date | P1 | ✅ | `cmd:library.filter` (`date`), `crates/ui-egui/src/panels/left.rs` (`date_row`), `crates/catalog/src/query.rs` (`date_groups`) | year → month → day tree with library-wide counts; a row filters the current source by that date. Active filters show as removable chips under the grid header (`crates/ui-egui/src/panels/chips.rs`, with “+N more” and Clear all), the header counts “N of M photos” (matching of the source's total), a badge on the top-bar filter icon counts them, and an empty result says no photos match the active filters |
