TOPICS IN THE CATEGORY USED THE TAG
But I can’t track topics within a category with a specific tag. In this case the system tracks the topics with this tag with all categories https://meta.discourse.org/tags/c/howto/10/voting
I don’t think it is a bug. Discourse has not implemented a feature that allows for tracking tags within a specific category, so what you are seeing is the expected behaviour. Tags are intended to cut across categories, so when you watch a tag, it is normal that you will get results from numerous categories.
That’s true and for this reason, we can subscribe for new topics with this tag on the page of this tag, like this one: https://meta.discourse.org/tag/voting
But when a user filters topics by category AND tag as in this case https://meta.discourse.org/tags/c/howto/10/voting I think the user wants to subscribe for topics with this tag not from all categories but only from this specific category.
May be as a plugin? I mean, is it possible in general?
I saw the “Saved searches” plugin and thought that this could be done on its base. Instead of specific words, the user should choose a category and a tag to watch.
If I need to change the setting I simply change it on the destination page (not in the Notification preferences). Because if I’m notified and would like to change it, then I always know the destination and can change the setting there.
