Remember quick filter setting per folder

[cug]

It would be great, if Thunderbird could remember the quick filter setting on a per folder basis. In macOS Mail I can set certain folders to only show "unread" messages (e.g. mailing lists, or daily maintenance emails, etc.) and in others I might only be interested in another subgroup of emails.

Making the quick filter sticky is not what I need there, as different folders need different treatment. For me, this is mostly about only ever showing unread messages in certain folders, but there could be other useful cases.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

That was available up until Version 102 using the view toolbar button.  Unfortunately, it does not appear to be persistent in version 115.  Hopefully that is just a bug and persistence will return in an upcoming release.
