Thanks for the info. I have actually been using the different gadgets, including the one you mentioned - the Google Calendar gadget that places a check-mark in the date. It's OK, but I prefer the easy survey of my calendar to see when something is due. Most of my repeating tasks are in their own "folder" to make them easy to see (or filter out) in the standard web page view. Doesn't look like there is an equivalent for the calendar.
BTW, some mysterious entries appeared in my Toodledo calendar today (not the Ical, the "gadget" calendar). It says they were created by Toodledo. I don't mind but it seems like the developers might want to know.
I really like the ICal subscription - I can see the tasks on their due date in my calendar. But my daily repeating tasks fill up the calendar. Is there some way to separate the repeating from non-repeating tasks for the purposes of the Ical connection? Thanks.
