Metadata about a message that seems to be missing in TB 3.1

I had written JAWS scripts to fine tune speech in Thunderbird 3.0.  I 
knew there were some significant user interface changes in the 3.1 
version, so have only just gotten around to upgrading when I had some 
time to revise the scripts as well.

I have resolved most compatibility issues, but not yet found a way to 
convey certain meta data about a message that I previously was able to 
obtain and make convenient speech-wise.  Specifically, I am not finding 
data about wehter a message was forwarded, replied to, or its size in 
bytes.   I have analyzed the tree of MSAA properties in detail.  It 
appears that useful info was dropped in the upgrade to TB 3.1.  I hope I 
am mistaken, so ask for anyone's help in obtaining such info from the UI 
(in TB 3.0, it used to be contained in the AccName string of a message 
item object).

Another issue was also present in TB 3.0, and I am just reporting it 
now.  The AccFocus property of a message list object is not set with the 
value of the index position of the message that has focus in the list 
(it remains at a value of 0).  This would be useful info to have.  Right 
now, I have to traverse the list of messages, checking their states, 
until I find the first one with a focused bit set in the AccState 
property.  I hope this can be fixed in a maintenance release of TB 3.1.

Thanks,
Jamal
