Version: 1.42 (using KDE KDE 3.3.2) Installed from: Compiled From Sources Compiler: gcc-3.4.2 OS: Linux The warning when closing multiple tabs requires a "do not show this message again" option. In most cases, the warning is unnecessary and excessively annoying.
It's already configurable. Adding a checkbox to the dialog is a bit ambiguous whether it in future will always quit or always close current session.
FYI, Configure Konsole->General->Confirm Quit when closing more than one session.
