Extremely helpful add-on to manage contacts and to sync them via carddav. My critics is with the date format. As end user it's completely irrelevant for me in which format dates are saved internally. But to display and edit dates I want to have a format, which corresponds to the locale/region, like "DD.MM.YYYY". The required format "YYYYMMDD" to enter birthdates is suboptimal - kindly expresed.
This review is for a previous version of the add-on (33.4).
