Work on Project Heartbeat 0.15 has already started in the beta branch, this update which is codenamed Goth Girl School Idol Club. Among the new features is the all-new UI Skin Editor, with complete workshop integration like you are used to! With this new custom tool, you can create your own skins. Currently there is no documentation on how to use this tool, However reading the size and anchors article from the godot documentation might give you some basic clues on how to get started! The skin editor features a resource management system to import your own fonts and textures, you can edit all the UI components such as the clear bar or the song title by using the inspector on the right hand side. Additionally the system supports animated textures everywhere, which means that anywhere you can place a texture, you can make it animate. Currently this feature is a bit WIP so you can't change hte FPS yet, that will come soon. The tool is heavily inspired by the Osu! Lazer skin editor, it might be a less pretty but it more than makes up in the customizability department. You can copy the default skin (and in the future, any skin you are subscribed to) to use as a base for your own UI shenanigans. Yahoo has already uploaded the first skin to the workshop, please check it out! I hope you enjoy this new feature.
