Good replacement for Apples calendar

This app is well worth the price, as it removes some annoyances of Apples calendar app. The scrolling month and week views, along with the ability to add the times of events into one field using the 24-hour clock (rather than clicking in hours and minutes separately), are among my favourite features.
I have a couple of criticisms and requests:
1. At present, if you use many calendars, it is far too difficult to zoom in on 1 particular calendar and then go back to ones default view. I think we need a contextual menu item called "Focus on this calendar" that, when selected, would hide all items in all other calendars. This should be a toggle, so that selecting it one more time would restore the previous view.
2. Search doesnt really work very well, or at least not as I would expect it to. If I type something into the search box, I would like BusyCal to show me all items, wherever they are, that match the item, not only those that are already visible.
