I'm ok either way - tying it into your notification hub and/or adding it directly to this plugin. I'm thinking that people who install this extension will probably have your notifications hub extension installed already anyways. we can save that for another day though as I think we're all in alignment that adding more features can be in v2 of this extension or something like that.
that aside, I'm still using mybb so the terminology in play over there is probably different than what's used in flarum - I'll try my best to merge the two worlds together in my explanation for my use case.
in my b/s/t forum section, when you create a new thread/discussion a predefined thread prefix is required: want to sell, want to buy, want to trade, closed & sold, etc..
I have an automation cleanup plugin that checks within the b/s/t forum section for threads with the sold & closed thread prefixes, I believe 1 or 2x a day. once it detects them, it automatically locks and moves those threads to a b/s/t archive section for price posterity and to view what has and hasn't sold in the past. This same script also automatically moves threads into the same archive section that are I believe 4 or 6 months old.
In my use case, I think sending a notification/reminder to use the feedback system when a certain predefined 'tag' is applied/added to the discussion would cover a lot of the bases. not 100%, but probably 75% or better.
like what treyb mentioned earlier, a lot of b/s/t threads/discussions on my forum are for singular item sales and/or someone who is selling several items within the same thread.
I'm definitely open to seeing what ideas others come up with though for sending reminders.
