I had a good week. The long-awaited incremental tagger is ready, and the program supports some more document types. You will get a yes/no on update, but it isn't a big deal.
When you open the manage tags dialog on several thumbnails, it now has a '±' button that lets you tag the files 'page:1', 'page:2', 'page:3' and so on. You can set the namespace (or no namespace), the starting point (so you can start at 'page:18' if you need to), the 'step' (so you can count by +2, or even -1 to decrement), and even prefix/suffix for the number if you need to decorate with 'page:x (wip)' or something.
