I do all of these things on a regular basis.  I have 5 calendars in  
my sidebar and I definitely switch between them.  Sometimes I need to  
add an event to the office calendar, other times to my personal work  
calendar.   I am switching calendars a lot.

With 5 calendars in the sidebar,  The screen is often over full with  
events -- even though I am running on large (1920 x 1440) monitor  
with an enlarged Chandler window -- so I am often activating and  
deactivating calendars using the checkboxes.

I also change the view regularly because the meetings are a week or  
two ahead of today's date.

In short, all three of these situations happen regularly for me.  And  
they happen after I rerun Chandler, and they happen the second,  
third, and 10th time that I do them.

Additionally, double clicking to create an event is very slow, and I  
frequently find that I have created two events because I thought that  
the mouse didn't click or something like that.

I also find the the performance of syncinng (no surprise) is a  
usability barrier.

This is all from my experience with the Intel Mac build.
