Are the year tabs supposed to be gone?

Also I think it might be better to have the favorites tab always present (either as "Favorites" or with the star icon) and just show "No favorited assets yet!" if empty.

Also it looks like the defaults don't work quite right, when I opened it, nothing from the assetpack was favorited.

Also maybe auto-favorite local uploads because they'll probably be likely to use the models they add themselves

@rutmanz you have to clear storage if the thumbnails + years are not showing up

everything else works but the auto-favoriteing of uploads and some defaults (dozer, for example) still isn't happening for me

I found the issue. You must run

git pull && bun run assetpack

and then restart the bun server.

looks like the defaults are there now but uploading doesn't favorite them
