It would be great if the calendar plasmoid could use ical files. It then could correspond with korganizer calendar. I'd love to see in the calendar widget the dates marked when I have appointments and by hovering over the date it could display a bubble with the exact appointment terms like start, ending and description. And on clicking on a date in the calendar widget either the korganizer dialog for adding a new appointment should open or a similar simple dialog for just adding start, end and description. 

So I could see all relevant dates at one glance (and adding new) without having to open korganizer. 

Gdeskcal can do this (but only set a start time, no end time) but it is not looking good in KDE4. And as we now have a calendar plasmoid that sits on the desktop it would be great to really make use of it.
