The ability to collaborate with multiple departments within our organization at once is very powerful! It also allows for easy communication between different teams without having people in person or via phone calls/Skype etc..
I dislike that it can be difficult sometimes when you're trying to find something because there's so many tabs open of things going back & forth across internal emails which are constantly being updated as we work through projects together internally - especially if they have been working remotely from home due to COVID-19 pandemic restrictions (which most do). We use this tool primarily during business hours but some times afterhours too since not everyone works 9am til 5pm anymore like us either :).
