Here is version 1.2 of the plugin. It has a small tweak to facilitate proper HTTPS support. The tweak is a little hacky as I can’t for the life of me find a non-hacky way to do this in the WordPress manual.
The plugin can be considered fairly stable now as I’ve used it in most of my blog posts over the last couple of months without issue.
Anyway, download version 1.2 here.
