* Make new sessions start in the active session's current working directory
(if both sessions are of the same type - otherwise the default working directory
for that session type is used)
* When creating a new session via the tab-bar button or "Ctrl+Shift+N" shortcut,
make the new session the same type as the active session.

This behaviour will probably be made an optional default, pending feedback from the KDE4 Alphas/Betas
