I'll still post the answer as it may help someone else. Plus I'd already written it before I saw you'd found it The options to disable/delete/rename are available from the context menu of the list of menu items on the left.

Just a heads up to anyone using the skin - there haven't been any updates recently because I've been working on another project which will directly improve this one. In the next couple of weeks I'm going to be back-porting a lot of improvements but, due to the nature of how it's going to be easiest for me to do it, it's quite possible some features will be temporarily dropped. So, when you get an update in a week or two, if there's any feature you can't live without thats missing please let me know and I'll get it re-added ASAP.
