Dear WADA,

How do other email clients deal with this situation on the commonly huge
IMAP folders of Gmail ?

I think this is a rather critical bug of Thunderbird. As you say, "some
major IMAP servers don't notify flag status change via IDLE", and Tb
should be able to deal with this situation OOB. If I understand
correctly, the workaround only works well with small IMAP folders.

Are there plans to fix this 2.5 years old bug ?

Regards,
