We're trying our best to bring top features to you. Our apps are products of thousands hours spend on support, development and tests. We understand, sometimes you may need something custom and you've got time constraints.
How it works?
Any customer can request a new app, feature or customization and sponsor its implementation. You'll get a chance to influence the shape of the end product.

Once the app or a new feature will be implemented, we will release it publicly via Atlassian Marketplace.
