Long-running, infinite threads

Some Twitter users create long-running threads to group all tweets within a certain topic or project. This happens over a longer period of time. Sometimes spanning years.
It might be interesting for Typefully to support this. I'm not exactly sure how it would need to work, but perhaps you could "pin" certain threads which you can then easily add new tweets to.
On the technical side, this would require Typefully to track the ID of the last tweet in each thread, to then reply the next tweet to, and so forth.

Personally I'd use this to keep track of all of my WIP project updates in one place. Ideally I'd like Zapier support for this feature too.
