Version: 2.3.2 (using KDE 4.3.2) OS: Linux Installed from: Mandriva RPMs KDE4 konsole should be able to detect/import setting/sessions from KDE3. Also, the shortcut CRTL+ALT+M should be re-added for quick sessions access.
I"m not sure it is worth the effort to code this. We are on 4.7 now days and I don't know any developers who have a KDE 3 system running.
I know many who use KDE3's konsole under KDE4 or even under gnome. But you may b right, it just might not be worth.
