I have just discovered Checkvist and I am very impressed with your work. It is a shame it took me so much time to find Checkvist as it is exactly what I was looking for. Now I hope you will keep the system on ;)
Recurring tasks are not handled as expected. If I complete a recurring task, the expected behavior is that the due date is changed to the next due date. But this is not working. Also reloading the page and clearing the browser cache has no effect. The completed task is still displayed (stroked out) with the old due date. Is this a bug?
Javascript error: "show all notes" Javascript error with "show all notes" and the same with "hide all notes". I use Opera (based on Chrome) It needs exactly 4 clicks to have this function working without an error an also 4 clicks for hiding all notes.
There is a bug if a list name contains quotation marks like: my list "this titel" The item for the due date includes some parts of the list name, the parent item and a single quotation mark... It seems that the string for the list name is not escaped correctly.
