Thunderbird 102.5.1 (64-bit) Windows 11

Since a few years back my Lightning calendar lost all the color backgrounds for categories, which was a plugin that does not work anymore. The small sliver of a color bar on the right side of the event on the calendar page is not helpful to see in a glance what category is coming up in a few days. I have several job categories such as Photography, Video Recording and Audio Job. If I can color code AND SEE them at a glance when I am in the month view is a great help. I am not sure what purpose it serves to have a thin slice of color on the right side of the event! If the whole background of the event line has that color it will serve some purpose. I researched and tried all the css hacks and config edits but nothing seems to work. Is there any help that we can get? I see that others are also looking for a solution that works in the latest version. Any help would be greatly appreciated. Thanks.
