I'd like to open new "threads" when chatting with someone. Each thread would be displayed in a different column and both you and the other can close the thread, merging it on the main thread.
interesting idea. Personally I don't see a use case for me. Generally the human mind is already pretty good at following multiple topics on a discussion at the same time.
Maybe you have an idea of how this would look like in the user interface? Would also be good if you supply more substance to possible use cases.
Again thanks for your feedback
