 We welcome all contributions, but keep in mind that we already have a lot of the UI designed. If you wish to work on something with the intention on having it included in the official distribution, please open an issue for discussion and we will give you what you need from a design perspective to proceed. If you want to make *changes* to the design, we recommend you open an issue with your intentions before spending too much time, to ensure no effort is wasted.

+Please make sure you are familiar with the [development and testing](https://github.com/ppy/osu-framework/wiki/Development-and-Testing) procedure we have set up. New component development, and where possible, bug fixing and debugging existing components **should always be done under VisualTests**.
