I am trying to replace some of Gmail-frontend use with Icedove in Debian. I however find some limitations in Icedove, but possibly, because of Gmail's limited export tool. I imported Gmail's CSV file into Icedove but I find it partial. No contact autocompletion. Fields in Address Book are without any prioritasion of the full fields, but showing much blanks in Fig. 1. Other thingsmany name fields are missing so proposing me that Gmail's export tool is partial. I start to type a new message. Icedove does not appreciate any of the new imported contacts. You have to type explicitly each address field again in Icedove. This is rather impractical with > 1000 contacts. ...Fig. 1 Address Book main view for Gmail-export-tool contactsSample of Gmail-export-tool output .csv where you see many fields but contacts are non-fullFirst Name,Middle Name,Last Name,Title,Suffix,Initials,Web Page,Gender,Birthday,Anniversary,Location,Language,Internet Free Busy,Notes,E-mail Address,E-mail 2 Address,E-mail 3 Address,Primary Phone,Home Phone,Home Phone 2,Mobile Phone,Pager,Home Fax,Home Address,Home Street,Home Street 2,Home Street 3,Home Address PO Box,Home City,Home State,Home Postal Code,Home Country,Spouse,Children,Manager's Name,Assistant's Name,Referred By,Company Main Phone,Business Phone,Business Phone 2,Business Fax,Assistant's Phone,Company,Job Title,Department,Office Location,Organizational ID Number,Profession,Account,Business Address,Business Street,Business Street 2,Business Street 3,Business Address PO Box,Business City,Business State,Business Postal Code,Business Country,Other Phone,Other Fax,Other Address,Other Street,Other Street 2,Other Street 3,Other Address PO Box,Other City,Other State,Other Postal Code,Other Country,Callback,Car Phone,ISDN,Radio Phone,TTY/TDD Phone,Telex,User 1,User 2,User 3,User 4,Keywords,Mileage,Hobby,Billing Information,Directory Server,Sensitivity,Priority,Private,Categories,,,,,,,,,,,,,,1234567@gmail.com,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Normal,,,,,,,,,,,,,,,,,123456@mailinator.com,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,Normal,,,OS: Debian 8.7Icedove: 45.6.0
