Woa nice mate! Excellent work!!!!
Most of my problems were about pop-up window sizes... most of them go waayyy below/over my screen... Why don't you load the emails and settings on new tab instead of a popup window?
Also some popup windows load in the center region of the viewport and other on the window screen.
There are many nice scripts that resemble facebook like autocomplete, it would be a very nice addition to the whole thing
Are you thinking of releasing this or it a closed project?
I'd really like to take a look at it
BUG: contact delete doesn't seem to work... actually it works but then it can't reload the center region
this.centerContactsPanel.contactsStore has no properties
