Bug 134991

Version:           1.9.4 (using KDE 3.5.4 "release 79.1" , openSUSE )
Compiler:          Target: x86_64-suse-linux
OS:                Linux (x86_64) release 2.6.16.21-0.21-smp

I have KDE 3.5.4 running and I use KMAIL 1.9.4. 
Composing draft mails is somewhat annoying because there is no possibility to save the draft without closing the draft composer window. Very often prof. work requires that you start composing mails, save the draft for a meantime period (to avoid any losses of your work, even if one accidentally closes KMAIL or a crash happens), switch to another application, come back to Kmail and continue editing the (still open, but saved) draft. This is especially true for long drafts - you don't want to loose your work, but Kmail requires you to close and reopen the composer window to be on the save side. That is really time consuming and in my opinion not state of the art.  

The possibility to keep a draft open and still save the current contents is e.g. provided by Mozilla Thunderbird. It would very much like to see that feature in Kmail, too. 

This request is similar to the bug/request 32305. Bug 32305 is marked as closed. However, in the present Kmail version there still is no feature available for saving drafts without closing the composer window.
