Bug 222240

Version:            (using KDE 4.3.3)
Installed from:    SuSE RPMs

I don't know if it was intended or not, so hard to tell if this is wish/bug, but in general, from behaviour it is a bug.

Run KMail. Click on outbox. Create new tab. Click on sent-mail. Click on outbox. You should see outbox in the current tab, but instead KMail switches tab, and leaves the "current" tab not changed at all -- i.e. (1) tab outbox, (2, "current") sent-mail.

The correct behaviour would be setting both to outbox, and no switching. Various of reasons:
a) user wanted current tab to be X folder, if she/he intended to switch tabs, she/he would do this
b) it confuses the user, switch changes context, if you have multiple tabs, how do you get back fast and easily to the original tab?
c) this is inconsistent with other KDE apps (Konqueror, Konsole, Kate, ... you name it)
d) there is nothing wrong in two views of the same content
e) it limits the possibilities, like frozen searches: https://bugs.kde.org/show_bug.cgi?id=149496

So, please just change the folder as user asks, and nothing more.
