why I like Google calendar

1. Uncluttered UI.Rather I should say, a, no-nonsense UI.
2. Drag and Drop does most of the things.....no save button or delete button in the main screen.
3. Really like the way, the "what" and "when" fields change from uneditale to editable,when you move the mouse over it....
4. Ability to customise the view, for weekly,monthly, and next n days.
5. The agenda for the day comes to my mail everday.
6. The use of basic colors...typical google approach towards color selection.
7. I have not had to use the Help link till now(is there a help link??).
   

some things I would like to see:

1. The screen looks basically like an excel sheet,so, the user should have the ability to change the size of each cell(the way it is done in excel).
2. Should be able to change the month(and year), without clicking again and again on the >> button.
