Hey All, I just complete the front-end of an Offline Circulation Firefox Extension for Koha. As of now, it stores all the necessary data. Now it just needs to get it to Koha. I've been talking to Josh about how to do that. I'm looking for anyone who might volunteer to help on this aspect. Also, the extension is ready for translation, so if anyone wants to add French, or any other language to it, just let me know and I'll send you the neccessary files for translation.
I've also made it part of my project on sourceforge, koha-tools. Everything I've been working on involoving Koha is in the koha-tools subversion repository. That includes my other firefox extension, the activity simulator, the custom reports I've written, a few tools for fixing data problems in koha and in marc records, and the scripts and classes I wrote to move data our of our current ILS and into koha.
