You must have missed this bit as part of the Changelog
Story:

An indie dev will adapt to feedback given and adjust the GUI and game engine accordingly in the early releases of a game, so it takes time to get a GUI and engine that the majority like, what you have to understand is that this game is still in its infancy.
