Dear developer, I love your AddOn it covers so much of missing development on Thunderbird! But I think a found a serious BUG. When I drag and drop a category on the left side just under the dynamic address book search "all contacts" to another position within "all contacts" the category gets deleted together with the whole contacts.
Same happens, when I drap and drop a category from my addressbook to "all contacts", the use case obviously wouldn't make sense, but shouldn't end in such a destructive behaviour.
Thanks for reading.
This review is for a previous version of the add-on (33.4).
