[Dev] wxSynchronizeWidget "hints" and such

[Alec Flett]

Before Bryan leaves town, I'd like to spent some time talking about the 
"hints" mechanism that John and I have discussed here and there. This is 
basically the mechanism that gets collection change hints out to the UI 
via the blocks and wxSynchronizeWidget. I'd like to meet after lunch 
today, say 1:30pm PST. Please e-mail me or just come find us if you'd 
like to participate...
