in the readme it says you can click a checkmark next to the 'Save' button at the transmog vendor to load a queued set. This does not appear to be there anymore. The code to queue a set does appear to be working still, so I'm assuming the button's removal is a bug.

The button was changed to the "Import/Export Options" gear icon button. Clicking that button will bring up a dropdown that has the option to load the set. I'll update the readme to reflect the change.
