Rated 5 out of 5 stars

After applying the latest update (carbook 20.7) the close, minimize and maximize buttons are gone. Disabling cardbook and the buttons are back.

Is anyone else experimenting this problem?

Thanks.

UPDATE: I would like to congratulate the developer to give such a great support. The issue will be fixed in the upcoming update, I assume it will be rolled-out soon. In the meantime he also provided with a temporary solution.

This review is for a previous version of the add-on (20.7).  This user has other reviews of this add-on.
