AssetHoard v0.1.20: A proper control panel for the 3D and material preview

AssetHoard is a local-first asset manager for game developers and digital artists, and this release gives its expanded preview a real control panel: live environment, surface, mesh and material settings you can drive while the model spins. Alongside that, saved default views, smoother selection and navigation, tidier dropdowns everywhere, and a round of fixes for larger libraries.

🧊 A proper 3D and material preview

The expanded preview grew a real control panel this release: environment, surface, mesh and material settings you can drive while the model spins.

Live controls for the expanded preview: environment, surface, mesh and scene settings sit in a panel you can drive while the model spins.
The right controls for the right asset: models get Surface controls, materials get a Preview mesh picker.

Material maps, one toggle each: every texture map on a material is listed with a live enable/disable switch, so you can see exactly what each map contributes.
Roles read from the file, not guessed: texture slots come straight out of the GLTF and FBX data instead of being inferred from filenames.
Fix a missing texture in place: when a model points at a texture that isn't there, AssetHoard ranks likely replacements and lets you pick one (or browse for it). The choice is saved as an override you can revert.
Harder-to-render textures still preview: TGA, DDS and EXR references decode on demand rather than showing nothing.

📐 Other 3D improvements

.sbsar materials get a thumbnail, extracted from the embedded icon.
Save a default view (orientation and zoom) for a 3D model, so it always opens framed the way you want, now including Blender and packaged models.

🖼 2D image backgrounds

See how a sprite or image looks on dark, light or transparent backgrounds.

Pin a light or dark backdrop per 2D image instead of the default transparent one.

🖱 Smoother selection and navigation

Back/forward history popout: press and hold (or Alt+click) the back/forward buttons to jump to any point in your navigation history.
Scroll position is remembered per view, so stepping in and out of bundles keeps your place.
Marquee drags auto-scroll the grid when you reach the top or bottom edge.
The scrollbar no longer clears your selection when you grab it.

🔽 UI tidy-ups

Dropdown consistency: styling and behaviour across the app has been standardised.
BPM shows on audio assets when it's been tagged.
Sort chevrons point the right way again, with a stable name tie-break so equal rows keep a consistent order.
Light theme polish: darker subtle text, zoom buttons visible on white backgrounds, audio waveforms on a proper background, models without stray gridlines, transparent 3D thumbnail captures, and tidier file-extension badges.

🗄 Solid backups and big libraries

Several issues that only bit larger libraries are fixed:

Backups over 4GB now succeed: the backup enables zip64 and streams the database instead of loading the whole thing into memory.
Assets stay fully searchable on huge libraries.
Restoring a backup repairs the library: thumbnails, archive caches and missing-file state are rebuilt after a restore.
Large import resume: UI improvements reduce the intermittent freezes on "Setting covers".

🐛 More polish and fixes

Manage Tags can remove a tag that's only on some of the selected assets, not just tags shared by all of them.
Category counts update consistently when you apply a category to a bundle.
"Reveal in folder" falls back to opening the containing folder when it can't highlight the file, instead of just failing.
Flicker on import when setting covers is fixed.
Packaged .gltf models render correctly: a bug meant their declared .bin buffers weren't being staged alongside the model.
Clear All Data in settings now clears the archive member cache too.
Image indexing settles down: assets whose file is missing on disk no longer keep re-indexing every launch.

Happy hoarding.
