Timeline & pinned messages
Keep the important context visible above the day-to-day flow of the channel.
Any card can be pinned to a channel's timeline, keeping decisions, key documents, or recurring reference material visible without needing to search for them every time. Pinned items stay attached to the channel until someone with permission unpins them.
The timeline view gives you a compressed history of a channel's key moments, useful for onboarding a new member quickly or for catching up after time away without reading everything that happened in between.
