set-default-columns

Provides ability to set default visibility of columns in the thread pane.

By default, Thunderbird shows following columns for newly detected folders.

• threadCol
• attachmentCol
• flaggedCol
• subjectCol
• unreadButtonColHeader
• correspondentCol
• senderCol
• recipientCol
• junkStatusCol
• dateCol
• locationCol

However, even if you want that the "Priority" column is shown for all folders, for all users, there is no way. This addon provides a preference entry to customize the list of default visible columns of all folders. For example, if you want the column "Priority" is visible by default, then you'll put a directive into your MCD configuration file, like:

lockPref("extensions.set-default-columns@clear-code.com.columns", [
  "priorityCol",
  "threadCol",
  ...list of other default columns...
  "locationCol"
].join(","));

And, you'll rearrange default columns via extensions.set-default-columns@clear-code.com.order. The format of its value is same to extensions.set-default-columns@clear-code.com.columns.

Note that there is nothing to do with extensions.set-default-columns@clear-code.com.order about order of default columns. Without extensions.set-default-columns@clear-code.com.order preference, it is not guaranteed.

This is mainly designed for corporate-use.

Note

Here is the list of default columns.

• threadCol
• flaggedCol
• attachmentCol
• subjectCol
• unreadButtonColHeader
• senderCol
• recipientCol
• correspondentCol
• junkStatusCol
• receivedCol
• dateCol
• statusCol
• sizeCol
• tagsCol
• accountCol
• priorityCol
• unreadCol
• totalCol
• locationCol
• idCol

Note that there is a case that specified columns are not shown. By default, senderCol and recipientCol column are not shown without additional configuration setting.

Here is the setting to enable these columns:

lockPref("mail.threadpane.use_correspondents", false);

With above setting, instead of correspondentCol column, senderCol column is shown in Inbox folder and recipientCol column is shown in Sent folder.
