I continuted to work mostly on Query bugs -- all except for #1897 & #2737. It's become clear to me that the design of Query is flawed (and the code is getting too crufty) so it will require a major overhaul. Fixed bugs:

• #2701: events added/removed from collections don't show up in All collection right away (collection update problem)
• #2740: double clicking in the calendar view of user defined collection doesn't create a new event
• #2510: unstamped items continue to show in the filtered collection resultset
• #1897: Tool bar buttons don't persist state
• #2510, #2682, #2749, #2699 (except for Mac) Fixed with a patch that goes at the root cause of the Query bugs, by taking a new fresh design approach. This patch that was not approved by Ted, so I entered a new bug #2756 sumarising the problem and reassigned these bugs to Ted to be fixed in the post 0.5 Query rewrite.
• #2737 CPIA view skin choice makes the whole Chandler window grey (not fixed in 0.5)
• I replace the bugridden ad-hock delete code in LoadMainViewRoot with a cloud delete, which didn't exist at the time I originally wrote it. (not fixed in 0.5)

I'm glad to see 0.5 behind me. I feel good that I actually fixed all my blocking bugs -- even if some of the changes were considered too risky for the release.
