Hi, I am looking for some plugin for expanding groups in writing mail window adress book. I found some plugins like "NotTo", " AddExpandedList" or "PopMailListRecipients", but I have some issues. NotTo doesn't work at all, not compatibile vit current version. AddExpandedList will not add proper context menu on group. PopMailListRecipients works but the actual work with it is terrible. I have now over 600 mailing contacts in different groups. Now I wanted to send email to my - lets say - co-workers. That is a group of co-workers. But Thunderbird allows only sending mail to whole group. I need to select from my co-workers only about 30 recipients. How to do that? I can barely find their emails in whole adress book panel with over 600 contacts, and by PopMailListRecipients plugin, loading whole 70 adresses into recipients and than manually deleting 40 of them definitely is not what I want. Simple thing, I want to expand groups as a ... windows folder tree with contacts in that group. Also, my groups are not shown, in dropdown on the top of adress panel in writing message window. Any tips? Thanks.
