Filters were global — switching from "Discarded" to a folder kept the
discarded flag, switching from a heap to All Photos kept the heap
filter, etc. Confusing because the user couldn't tell what state any
section would be in until they got there.
Now each "section" remembers its own filter state independently. The
in-memory map is keyed by section id ('all-photos', 'rated',
'discarded', 'duplicates', 'tags', 'folder-{id}', 'heap-{id}'), and
navigating saves the current section's state under its id and
restores the destination's. Sections you've never visited start with
their intrinsic preset on top of INITIAL_FILTERS.
filterStore additions
- currentSection: string (default 'all-photos')
- sectionFilters: Record<sectionId, FilterState> — in-memory snapshots
- sectionPresets: Record<sectionId, Partial<FilterState>> — the
intrinsic filter that defines each section, used by clearAll
- navigateToSection(id, presetOverrides):
1. snapshot the current FilterState slice into sectionFilters[
currentSection]
2. record presetOverrides in sectionPresets[id]
3. set currentSection = id
4. load sectionFilters[id] if a saved snapshot exists, otherwise
apply presetOverrides on top of INITIAL_FILTERS
- clearAll: now resets the CURRENT section to its preset rather than
jumping to all-photos. The user explicitly clicks All Photos to
navigate.
- snapshotFilters() helper extracts the FilterState slice cleanly so
control fields (filterBarOpen, the maps themselves) don't leak
into per-section state.
URL sync
- writeUrl serialises currentSection as ?section=… (omitted for the
default 'all-photos').
- parseUrl reads it back into currentSection on hydrate. Per-section
memory is in-memory only; reload restores the current view but
not the other sections' saved states (acceptable for MVP).
LeftSidebar
- applyLibraryNode now dispatches navigateToSection per node, with
the appropriate preset:
all-photos → {}
rated → { ratingMin: 1 }
discarded → { flag: 'discarded' }
duplicates → { duplicates: true }
tags → { groupBy: 'tag' }
folder-X → { folderId: X }
- isItemActive collapses to a single check against currentSection
for both library nodes and folder rows. Dropped the old
selectedItem local state and the per-field active probes; they
were doing the same job in a more fragile way.
HeapsPanel
- Heap row click → navigateToSection(`heap-${id}`, { heapId: id })
- isFiltered uses currentSection instead of filterStore.heapId
- Deleting the currently-viewed heap navigates back to all-photos
via navigateToSection (was setFilterHeapId(null), which now lives
in the section model).
User flow:
1. Click Discarded → seeing discarded photos.
2. Open FilterBar, set Rating ≥ 3 — discarded section now has rating.
3. Click Library "Library" folder → no rating filter, just library
contents.
4. Open FilterBar, set media type Photo only — folder section now
has that.
5. Click Discarded again → restored to discarded + rating ≥ 3.
6. Click Library folder again → restored to library + photo only.
