Looking for feedback on KOrganizer event editing tools

Greetings -

I'm working on a project to improve the editing tools for adding
appointments, TODO entries, and journal items in KOrganizer. If you
have experiences and ideas to share we're looking for user input,
specifically regarding these questions:

- which of these tools do you use and how do you use them?
- what problems do you have with them?
- how could they be improved?

Thanks for your attention -

Erin
