@sam’s previous response to this request was

Watching/Tracking old Topics

I can see the appeal on unconditionally adding “tracked” categories into the “new” filter but technically making this work could end up being quite costly performance wise. Also, we have to keep a cap on new counts cause they are tracked in memory in the app, if you have 500k “new” topics it can brutally slow (and kind of pointless) Honestly, I am really unsure what the best course of action is here.
