           Summary: After deleting a message in KMail, the selected row in
                    message list pane should remain the same
           Product: kmail
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mmtsales at gmail.com


Version:            (using KDE 4.4.2)
OS:                Linux
Installed from:    Ubuntu Packages

When a message is deleted in the message list, the cursor goes down to the
following row and the messages above the previously selected row go down. This
behavior is repeated until the cursor reaches the last row in the messages list
pane, preventing the user to see the following messages unless he manually
scrolls the message list contents.
Instead, the cursor should be kept in the row that was selected before the user
deleted the message and the following messages should go up. I think this is
the expected behavior for most users.
Example:
Imagine you have a message list sized to display ten rows and the selected row
is #5. So, there are four more rows being displayed before the selected one and
five after. If you click DEL, the message in the selected row is deleted. After
this, I think most users would expect that the fifth row would still be the
selected one. There should still be four rows visible before it and five after.
Messages that were in rows 6 to 10 would be scrolled up to rows 5 to 9 and a
new message would be displayed in row 10. So you would always see the following
five messages after the one that is currently selected.
But this is not what happens. After deleting message in row #5, the cursor goes
to row 6. Messages that were in rows 1 to 4 are scrolled down to rows 2 to 5
and one new message is displayed in row 1. You have now 5 messages before the
cursor and 4 after. Deleting more messages will make the cursor eventually
reach row #10 and now you can't see in advance the next messages anymore. This
is a very odd behavior and makes it difficult to manage messages in folders
which hold very active discussion lists, for example. In folders such as this,
several messages are commonly deleted in a row if their subjects are of no
interest to the user and not being able to see the next messages slows down the
process of deleting messages significantly.
