Highlight new mails in virtual folders

[Cédric Macquat]

Hello,

I have only virtual folders on the sidebar. When I receive new mails,
the virtual folders containing new mails are not highlighted. Is it
possible to change that ? If I use only regular folder, by starting mutt
all regular folders containing new mails are highlighted.

If I understand right, the virtual folders are the result of a notmuch query.
My guess is: when I start mutt, I see the result of the last query. Only if
change to a virtual folder the query is actualized. And it's what
happens: when I change to a virtual folder containing new mail, just
after changing the virtual folder is highlighted. How can I have the
virtual folder highlight when I start mutt ?

Thank you!

Regards,

Cédric
