The bug that you listed is a SeaMonkey bug. I believe that the
equivalent bug for Thunderbird is:
Bug 487386
That bug has everything permitted within Bugzilla to scream for
attention:
[ux-papercut], [gs], [UXprio], 25 dups, 52 votes, major importance,
wanted-thunderbird, user whine with official "do not whine in BMO"
response, etc.
Yet unfortunately the answer to your question is "there are no plans
to address this bug".
Personally I think this is a travesty, and it is bugs like that that
get me motivated to improve our general qc process. Looking at the
papercuts list, I nominated it as a bug, but only got one supporter
for that, so it did not make the official first list. What we really
need is a group process
that we actually use to choose bugs
to work on where important stakeholds in Thunderbird
have the opportunity to influence which problems get addressed.
There are existing processes in both BMO and gs that attempt to do
this. I don't really understand why those processes are not used in
a more effective way to influence development. People have followed
our process, this bug is easily a top 5 bug we should be looking at,
yet we don't.
Perhaps others who have been more involved for the last few years
while I have been off in addon land can give a better answer to
this. But let's look to the future, what can we change to better
address these types of bugs?
