The ease of use, the ability to see who's active in the community, and the easy integration with Slack. It has made it easier to communicate with our development team and also helps us keep track of the current status of our projects. There's not much I dislike about Pastel. If you are looking for something that will help you stay organized, Pastel is a great choice. We have used Pastel for about 2 years now and we've been very happy with the service thus far. Our developers and designers have found Pastel helpful in keeping up to date with each other's progress. Not only does Pastel keep us organized but it's also helped us keep track of all tasks related to each project which helps us get things done faster.
