This has been implemented in SVN.

Sorry, but I can't find it in SVN. Maybe you misunderstood me.

I want to have serveral bookmarks on the left-hand side. 
I don't want to save my password and/or username in this bookmarks, because it is an free accessible computer.
When I want to connect to a FTP-server, I just want to double-click one of the bookmarks.
Then a dialog should appear: "Opening connection to <name>. Please enter username and password!", or if the username was saved in the bookmark: "Opening connection to <name>. Please enter password!"

Except of this little thing, kftgrabber is a really great ftp-client!!!

This feature is already implemented in 0.8.0 if you leave username and password empty in your bookmarks entry. It currently doesn't work for the left sidebar (but only if you select the entry from the menu) and it will be fixed ASAP.

SVN commit 632371 by kostko:

Properly handle userless sites in the sidebar as well.
