It would be great to have functionality that allows for the "plugging in" of a previous thread to a new thread to easily add context. In a way, this is like a manual, large-context, version of the planned Notes feature.
This could be implemented in two ways (and probably many more, but these are just examples). First, a cross-thread link sharing option that doesn't involve the external link sharing feature. This would be a kind of "internal" link that the Assistant would reference. This would help bypass the current limit wherein a chat link can only be accessed when search is activated. See an example of this below.
Second, through simply attaching a downloaded thread in a new thread query. This functionality already exists, but feels finicky and over the top.
An example of the utility of this: today I used the Assistant to help me use the Flightradar24 API to create a live tracking map for my local airport. I would love to be able to use all the context from that thread to inform my next project which would follow similar parameters in terms of my demands etc.: a train tracking live map for my local area.
