I had a look through Logs/FrameXML.log file out of curiosity earlier and noticed this:

1/22 17:34:34.895  Loading add-on BagSync
1/22 17:34:34.895  Binding header BAGSYNC is defined more than once in Interface\AddOns\BagSync\Bindings.xml
1/22 17:34:34.895  Binding header BAGSYNC is defined more than once in Interface\AddOns\BagSync\Bindings.xml
1/22 17:34:34.895  Binding header BAGSYNC is defined more than once in Interface\AddOns\BagSync\Bindings.xml
1/22 17:34:34.895  Binding header BAGSYNC is defined more than once in Interface\AddOns\BagSync\Bindings.xml

The header="" attribute only needs to be set for the first binding in the file and WoW will automatically group the rest of the bindings under this header (unless a different header is used further down, in which case any further bindings will be grouped under this second header).

This is a very minor problem though. I can't see any other problems occurring because of this.

I'm just being picky I guess.

Hey! Thanks for pointing this out. I'll add it to my list of things to update for the next version.
