-- SuperSimple style shows sub-gallery preview thumbnails, and in two columns.
-- Paging in text/security editor
-- Confirmation dialog before moving picture out of dated gallery
-- You can rearrange pictures while other pictures are still uploading to a gallery, without destroying incoming order of new pictures now.

-- Misc UI improvements elsewhere.
If you're curious what's coming next, I've been keeping my todo list updated.
