Hi! I just synced my Google calendars and my tasks are there too. I think that the sync works very well.
I do have one problem: my task categories are missing from the To-Do List. Is this a future feature or is there a way to sort my tasks by the Google category, or just show the category I'm interested in? I use my task lists a lot and my task categories. Thanks!

Korganizer handles calendars and To-do lists. When synching with google calendar and task lists, the google named task lists come in labeled like calendars. In the New To-do form, the calendar dropdown list lists only the google Task lists (and Personal Calendar). All my To-do lists have appeared.

In the Calendar Manager (lower left side-panel) The To-do lists are also listed with calendars but their icons are distinct from calendar icons. More than one can be checked (activated) at the same time.

The categories shown in the To-do view have nothing to do with To-do list names. They are a place for tagging items.
