All right, it's fixed! The new version is
0.1.1.
The change was very minor. The CSS class on the <span> element containing the catalog number was changed from "time" to "catalog". Seems like a good change.
By the way, Myrkul, thanks for the promotional speech above!
I've been working on version 0.2 and I think it will be ready soon. The new version will add a command line interface, more flexible exporting options, and the ability to save custom export presets.
