We use feature requests to get ideas for new features to develop and for improvements to the app. The popularity of requests is one of the factors we use to decide what to work on next.
Note that many of the very popular feature requests (such as alerts/notifications) are also very large pieces of work. Even though we absolutely want to make them, right now we have to focus our resources on the highest business priorities.
This will ensure Railboard survives and thrives, and as it does, we will have a stronger capability to develop the very popular large features people want.
