Incompatible with TabUtilities Rated 3 out of 5 stars

Colorful tabs is great but sadly versions 19.8 and 19 are now incompatible with the Tab Utilities extension's appearance options.
Best to stay with CT version 17.8 which is compatible with Tab Utilities.

This review is for a previous version of the add-on (19.0.1-signed).  This user has a previous review of this add-on.
