 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 of 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.
