In kmymoney, when you need to choose a payee or a category, you just have to begin to type what you want to find, and there is a search-as-you-type function, which display all the corresponding categories, it's parents and childrens. It would be great to have that kind of behavior in Korganizer. Additionally, as it's possible to choose multiple categories in Korganizer, the combobox list should show checkboxes on each line you could select with the keyboard shortcut 'Space'. Reproducible: Always Steps to Reproduce: 1. Create a task 2. Use a keyboard shortcut to focus on the category textfield (cf. bug 305207) 3. Begin to type 'fr' 4. Categories 'Friends' and 'Africa' are shown in a combobox list, while categories 'Parent:subcategoryFR:subsubcategory' are shown in that combobox list on three lines, with "subcategoryfr" indented. I attached a screenshot of how kmymoney shows categories when you type 'mais' for instance, with all the parents and childes of the selected categories shown. This request is linked to bug 297769.

This would also fix the bug in the category list bug when you type 'ab' quickly, the first word starting with 'ab' is not selected. You have to type 'a', wait a few ms, then 'b' to get the same behavior you have in any list in kde.
