Mostly things people asked for after the Show HN.
PDF zoom now goes to 10x instead of 3x. The old limit was a library default I had never overridden, and it was not enough to read something small on a full page, like a QR code on a ticket. (#2, thanks @neuos)
OpenDocument spreadsheets (.ods) now show up in Open-with. They already rendered fine, but the MIME type was never registered, so tapping an .ods in a file manager did not offer Gander. Opening one from inside the app always worked. (thanks to sgc on Hacker News)
Screen reader support. Someone asked how Gander handles accessibility, I went and checked, and the answer was "not well". Now the back button, the photo viewer, web-rendered images and the file rows on the home screen are all labelled, and the search match count is announced as "Match 2 of 7" rather than "two sevenths". (thanks @FreedomBen for asking)
Still honest about what is missing: PDFs give a screen reader nothing at all, because the renderer produces bitmaps with no text layer. That is the same reason you cannot copy text out of a PDF or search inside one. Fixing it properly means changing the PDF library, which is a bigger job.
