Although there exists some code in the extension for storing and retrieving of lighning calendar categories it actually does not work.

Reproducible: Always

Steps to Reproduce:
Attached patch A patch for lighning category support (obsolete) β€” β€” Splinter Review
Hi out there,
i have fixed the problem with categories not showing up or at least
not synchronizing with google cal.
Actually Google has no support for categories yet (or never will have,
who knows?), but as a little workaround google calendar allows to
store extended information as part of an event. So I modified the code
a little bit just to store and retrieve mozillas category information
as an "extendedProperty". The category doesn't show up in google and
cannot be synchronized with Outlook (via Google Calendar Sync) but
it's visible in lightning/sunbird.

Axel, thanks for your patch. In order to get it into the tree, it needs to be reviewed. See for a list of reviewers. In this case, best would be philipp. So I set the flag to ask him to review.

A patch for lighning category support

First of all, thank you for the patch!

I'd prefer a more customized name to not clash with others who potentially use a such general name. I'd suggest "X-MOZ-CATEGORIES".

Use brackets even with one-line if(). Also, space after comma. i.e
        if (gdCategories) {
            item.setProperty("CATEGORIES", gdCategories);

After some remarks of the reviewer I modified the code to comply with the "holy" Mozilla Calendar coding conventions. ;-)
