Status: RESOLVED DUPLICATE of bug 622779

(Thunderbird :: Folder and Message Lists, enhancement)

Description

[Douglas Williams]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5
Build Identifier: Thunderbird/3.0

When I display my messaged threaded, and when the messages in a given thread are displayed collapsed (little clickable arrow at left of subject column is pointing to the right), the size field should display the size of the entire thread, not the head email in the thread.  Sorting by size should sort based on the entire thread's size, not the head email in the thread's size.  When not collapsed, it may still make sense to sort the field based on the entire thread's size even while displaying the size of each email individually.

When sorting emails to clean out a full inbox, it's nice to see the actual size of the thread you are considering deleting.  turning off threading and then sorting by size can cause you to throw away parts of a thread instead of the whole thread, so the fix is useful.

Reproducible: Always

Steps to Reproduce:
1. click threaded icon
2. add size field column to display
3. look at size of any thread -> it's the size of the first email, not the whole thread.
Actual Results:  
-> it's the size of the first email, not the whole thread.

Expected Results:  
-> it's the size of the whole thread.
