Don't mark old unread private messages as new

I like the new PM system to mark private messages as read / unread, but I have a little problem with that.

As many others, I use buttons on the navbar of my forum, and this one changes if you have new messages. The problem is it also displays the "New messages" button if you have unread messages, even if they are very old, so it's a bit confusing. Some people may want to have unread messages but that makes that button useless since it will always look the same. This didn't happen before.

I was wondering if there's an easy way to change that. I'm not sure if it's a bug of the new system, or it was meant to be like that; in the last case maybe a Javascript for those who prefer the old button behavior may be the way to go.

With Javascript you can store in the cache the date of your last visit, and use that to check if the unread messages are new or not, but I'm not sure what's the best way to do that.

Please post screenshots with the issue you are referring to marked.

hello

@Wecoc means that if you have 20 inbox messages and one of them is unread even if that pm is dated last year the system shows that you have New messages
for the system to shows No new messages all inbox messages must be read (new and old)

@jkh also said that

the 'New PM' now flashes when you also have a PM in your outbox - that didn't happen before, it only used to happen when there was a new PM in your inbox. I

Exactly. It worked fine until that last update on the PM.

I thought that could be the problem at first, but as far as I tested I don't think that's right. The problem is only in the inbox.

As I said maybe it's not a bug and it was meant to behave this way, but I would prefer to have the old behaviour instead, even if I have to modify a template or add a Javascript for that.
