I have seen a custom css workaround solution to add category colors into calendar events. That solution still relies on calendar events having to be categorized in order to support color functionality. How is it the year 2024 and Mozilla Thunderbird Calendar doesn't support event colors, independent of categories? This feature has been standard in most major calendar apps for literally decades now. All my Nextcloud calendar events are color coded (without categories), and won't sync to the Thunderbird app. Can Thunderbird please add this functionality?
