True, my mistake! I read too much into the mention of it as a built-in SMF feature.
Right, but you’re required to be in the same place at the same time… there’s a little barrier there. The utility to seeing that someone’s typing in the same topic also seems clear to me… on Meta, for example, if I see someone from our team typing a response I can comfortably move on to something else.
A separate page with presence makes it significantly easier to stalk or micromanage someone, and the utility aspect outside of that type of behavior seems less clear to me. Is there a use-case you’re trying to cover? Knowing that may help.
That’s ok! there might be someone else in the community interested in building it, that’s one of the benefits about working through features publicly.
