Version: 1.2.5 (using KDE 3.5.8) In Kontact the Kalender and ToDo components share Categories. I need them to have separate categories, like the KAddressBook component has it's own separate categories. Note that I've found the antibug to this bug, where a user is requesting that all the components have the same categories: http://bugs.kde.org/show_bug.cgi?id=88547 So maybe the best solution would be to have an option to have shared or separate categories.
