be able to create multiple different timelines with different tweets without having to delete all tweets
Sounds like something possible at some point.. If more people are interested possibly in v5.x update.
I've funnily already thought about this. As much as it would be a great idea, I decided not to at least for time being. But if users are interested and want this to be a thing then maybe.
