So I got everything working nicely, except that I was seeing events from all calendars, even disabled ones. I couldn't find anything in mKCal or the sqlite database to indicate which calendars were disabled. I decided to have a dig inside the Jolla calendar app to see how that did it, and found nemo-qml-plugin-calendar, which stores that and the calendar colours in a separate QSettings file in .config. I've added that directly to what I already had so I can now filter the evenrs, but should I have been using this plugin the whole time? mKCal is a little unpleasant, but at least it is available in the standard system, while it looks like it'll have to submodule the plugin if I want to use it.

Has anyone used it? Is it worth migrating over to it?
