I spent a chunk of time smoothing out the upload flow, because the old version still asked users to think too much before they could do anything. Now the app can usually tell whether you uploaded a single pin photo or a full board with multiple pins, so there is no need to pick a mode up front. That small change makes the whole feature feel much more natural.
Mobile uploads are better too. You can take a photo directly from your phone or grab one from your library, which sounds basic, but it matters a lot for a site built around pictures of physical collections. I also fixed a nice little workflow snag: when you create a new collection during upload, it gets selected immediately instead of making you go back and choose it again.
On the SEO side, I finally laid down the groundwork the site needed. There are now Open Graph tags for social previews, structured data for search engines, proper page titles across all 155,000 plus catalog pages, and breadcrumb navigation to help crawlers understand the structure. It is not glamorous work, but it is the kind of foundation that makes a small project easier to discover over time.
